Kokuyo Me 0.5mm Gel Pen Review

(Jeff Abbott is a regular contributor at The Pen Addict. You can find more from Jeff online at Draft Evolution and Twitter.)

It's not often at all that you see a new gel pen manufacturer enter the market. At this point, the big companies that operate in the stationery space already have various ballpoint refill pens available en mass, and they regularly churn new and updated variations on these. Bringing a new, cheap semi-disposable pen to market must be an extraordinarily large cost. So, when I see a pen from a manufacturer that I haven't previously associated with writing instruments, I jump at it.

Kokuyo is near and dear to my heart for the paper products they sell. Their paper is a good "middle of the road" quality, but it's paired with lower prices. It's nearly impossible to compare Japanese stationery culture with the American version, but Kokuyo feels like the ubiquitous brand that you can find at any office supply store. It's nothing special, but it's good at what is does. At any rate, it's about a thousand percent better than the paper products you find at any generic office supply store in the US.

Remember when Moleskine started selling pens? And they turned out to actually be pretty good? Well, that's kind of what's happening here with Kokuyo. The Kokuyo Me gel pen is fairly new, seems like a sleeper, but it actually hangs with the best gel pen options out there.

The Kokuyo Me pens are fairly new for the US market (forgive me if these pens are something that are really old news in Japan!), and I haven't seen much info or reviews on them so far. After trying one out for a while, I can tell you that Kokuyo's gel pen game is strong.

The 0.5mm black gel refill included with this pen is fantastic. It writes instantly and has no issues with starting, skipping, or bleeding. The ink is black and consistent in hue. The line edges are sharp and crisp. The only gripe I have about the refill is that I don't agree with the 0.5mm label they've given it. It's more akin to most 0.7mm refills, but that's a minor gripe.

The shape of the refill is very familiar. It's just a tiny bit different than the common Pilot G-2 refill, but it's essentially a complete match for other common pen/refill types. I've tried swapping with Uni Signos and Zebra Sarasas with great success. In theory, you could use the Kokuyo refill in other pens, or in machined pens made to use specific refills (like the Signo, for example). The only problem is, there aren't a lot of options in terms of Kokuyo's refills at the moment (at least for the US market). Black 0.5mm is the only option, unfortunately. I really hope that Kokuyo expands on their options for refill colors and sizes, but I guess it's still early days.

Getting back to the actual pen body, it's pretty standard fare with a couple of unique touches. The grip section is hard plastic instead of a rubberized, textured grip, and one side of the grip is faceted. This flat side of the grip is a nice place for a finger to rest while writing, but unobtrusive for those that prefer a different grip.

There's also a small round window between the clip and the grip section that shows you the numeric designation of the refill inside. It's easy to see the "05" through the window whether the refill is extended or retracted. This is possible because they've actually printed the 05 on the refill dozens of times to account for basically any possible placement of the refill inside the pen. Seems to me like something that was over-thought or over-designed as it doesn't really provide much value. Most pens in this price range have the refill size printed somewhere on the pen, but I guess being able to see the refill label is more accurate.

The "bell pepper" color I picked is a nice basic green. The pen body color has no bearing on the ink color — they're all black ink refills. There are several other pen body colors to pick from.

Vanness sell the Kokuyo Me gel pens for $4.50, which is in the ballpark for other comparable gel pens from the more well-known brands. Even if it's a little more than some options, I'd still say it's worth checking out. The refill that Kokuyo are using in this pen is promising, and I can't wait to see more options in terms of point size and color. Keep it up, Kokuyo!

Kokuyo Perpanep Notebooks - A Quick Look

(Kimberly (she/her) took the express train down the fountain pen/stationery rabbit hole and doesn't want to be rescued. She can be found on Instagram @allthehobbies because there really are many, many hobbies!.)

Perpanep is a line of 3 notebooks that Kokuyo launched a few years ago. The name Perpanep is a mashup of the words “pen” and “paper”. The papers used for the Perpanep are named Tsurutsuru, Sarasara and Zarazara. Each of these papers have a different texture, more on that in a bit. In addition, these A5 notebooks are offered in 4mm dot grid, 5mm grid and 6mm steno, which is a lined ruling that has a single vertical line through the middle of the page. For this review, I only have the 4mm dot and 5mm grid.

Set of 3 Perpanep Notebooks.

Each notebook comes with 60 unnumbered sheets/120 pages of paper. The notebook has a gray, flexible cardstock cover, and cloth binding tape which allows the notebooks to lay flat. Without the plastic “cover”, there is no decoration, branding or labeling, other than the small icon at the bottom center of the front, which indicates which type of notebook it is. There are 3 parts to that icon - a straight line, a slight wave and zig zags. This is meant to show the paper’s texture - smooth, slight texture, and more texture, respectively. The part of the icon that is in solid white tells you which paper is inside. I kept the thin plastic cover on the notebooks to remind me of the names of the different papers.

Thank goodness for these labels so I could remember which was which! It took me a while to realize that the diagonal lines echo the texture of the paper.

Just the icon at the bottom, which helps you figure out which notebook you have (this one is Tsurutsuru, which has the solid white line on the top part of the icon.)

The notebook’s binding allows it to lay flat when open.

Rather than writing with 48 inked pens, I picked the following pens for writing samples because of their nibs (stub, architect, flex, broad, etc.) or inks (shimmer, sheen, shading). I also picked a sampling of standard pens/markers that I’ve used for index card and similar reviews.

Fountain pens used: Leonardo Momento Zero (Medium), TWSBI 580 ALR (1.1), Pelikan M605 (Spencerian grind - extra extra fine with added flex), Esterbrook Estie (Broad), Leonardo Momento Zero (Fine Cursive Italic Flex from Stylosuite), Montegrappa Mia (Medium Monoc), TWSBI Go (1.1), Leonardo Momento Zero (Medium Architect), Franklin-Christoph 20, 14kt gold BB SIG), Scribo Piuma (Broad flex), Lamy AL-Star (Medium), Sailor Realto (Medium Fine.)

Standard pens/markers used: Tombow ABT Marker (color 245), Retro 51 rollerball, Parker Jotter XL with ballpoint refill, Parker Flighter with 0.7 gel refill, Lamy Tipo, Caran d’Ache ballpoint, Pilot G-2 0.7, Pilot Frixion 0.7, Sakura Micron 05 and Sharpie Fine Point.

Tsurutsuru is the smoothest of the 3 papers and has a slight ivory hue to it. Nibs just glided on them like butter on a hot pan. It was quite pleasant to write on, if you like really smooth paper. It held up to almost every fountain pen ink, except one - De Atramentis Document Turquoise, which isn’t surprising since most DA inks are fairly wet. It showed off shimmer, sheen and shading well. I generally prefer smoother to textured papers, so while this was nice to write on, but it might be a wee bit too slick. It felt a bit more smooth than Rhodia 80gsm or Clairefontaine 90 gsm paper. I don’t really have problems with sweaty hands or hand oils when writing but this might be one of those papers that could be affected by that, so your mileage may vary (or use a blotter sheet under your hand).

Note: Writing samples were used on the back pages of the notebooks so I can still use them from front to back when I’m done with testing it.

Writing samples on Perpanep Tsurutsuru - I don’t know why I wrote so big, lol.

De Atramentis Document Turquoise, used on the top line, bled through. No major ghosting and no bleedthrough with the other pens/inks.

Writing samples continued, along with some more normal sized writing.

No ghosting or bleedthrough on the back of the second page.

Lamy Dark Lilac 2024’s green sheen. I swiped it after it was dry and there was no smearing either.

Writing samples from standard pens and markers.

Is anyone surprised that the Sharpie almost bled through? There is some ghosting with the Retro 51 and Lamy Tipo, but overall the paper handled all the other pens just fine.

Next up is Sarasara, which was actually the first notebook I used because I hadn’t yet figured out the icon’s and what they meant, so I used all of the pens I had initially picked out (minus the Scribo which I added partway). Sarasara is a fairly smooth paper, but has just a wee bit of texture to it. It was very nice writing on it. I didn’t feel like my nibs were sliding all over the place. Like the Tsurutsuru, the only problematic inks/pens were the De Atramentis Document Turquoise and the Sharpie.

Sarasara writing sample.

You can see the bit of bleedthrough from the DA ink at the top and in the bottom ⅓ of the page. The speck of ink near the middle was because I accidentally closed the notebook before the left side had fully dried.

Not quite so gigantic writing on Sarasara.

Again, no major ghosting or bleedthrough.

Lamy Dark Lilac 2024’s greensheen is there but not quite as visible as with Tsurutsuru. The smudge was made before the ink was fully dry.

Everything wrote fine. The ballpoints had just a wee bit of a hard start but it was barely noticeable in the Caran d’Ache.

About the same amount of bleedthrough from the Sharpie on Sarasara as Tsurutsuru.

And lastly we have Zarazara. This was the most textured by far and I knew going into it that I would likely be biased against it because I do have a preference for smoother papers. But I tried my best to be objective and give it a fair shake. Zarazara isn’t just more textured, it’s also a bit more absorbent. The De Atramentis practically wicked itself out of the nib and into the paper. I wondered if the Extra extra fine Spencerian flex would catch on the paper but it did not. In fact none of the pens felt bad on the paper. The paper feels dry, as opposed to slick like the Tsurutsuru. It held up well to fountain pens, but it’s my least favorite of the three.

As soon as I started writing “Perpanep” on the Zarazara, I could see the ink soaking in like a sponge. After a few lines, I had a hunch it would still be fp-friendly, so I trimmed down the number of pens to cover shade, sheen and shimmer.

DA strikes again!

I kept expecting to see feathering but other than the De Atramentis, I didn’t really get that in large or small writing.

Looks good back here!

Even though the paper was able to show shading, sheen and shimmer, it felt like those various properties were a bit subdued, like it was absorbed into the paper. LDL ‘24 is still sheening bright green, just not as much as on the other two papers and it didn’t look quite a metallic.

The rougher texture of Zarazara gave the ballpoints a bit of a hard start but it was fine overall.

Sharpie bleeds through to the backside, as expected.

A few things to note that apply to all of the Perpanep notebooks:

  • Minimalist aesthetic - While I appreciate the simplicity of the gray cover and the cleverness of the icon to indicate the paper, it isn’t my personal style, so I would likely cover it up with stickers or put a cover on it. It would have been nice to have different colored covers to distinguish the different notebooks.
  • No page numbers - I am used to notebooks and planners that have page numbers but it’s not a big deal breaker for me.
  • Pages not easily removed (this is a good thing) - I was a little skeptical of the cloth tape binding and whether paper would get detached easily, so I opened it up to the middle and tried to pull out some pages and was not able to do so. Keep in mind that I haven’t put the notebooks through any rigorous, long-term use, but it did hold up to a few solid tugs.
  • Nothing to keep the notebook closed - This version of the Perpanep notebook does not have an elastic or anything else to keep the notebook closed. There is a premium version which has more pages and an elastic closure.

Overall, the paper in all three notebooks behaved well with the exception of Sharpie and a super wet De Atramentis document ink (it’s unclear if other DA inks would behave similarly or if there’s something in their document series that might cause this). My favorite of the three notebooks is Sarasara because it is very smooth with just a bare hint of texture, followed by Tsurutsuru which was very slick. Zarazara was my least favorite but it wasn’t a bad paper by any stretch. It wasn’t unpleasant to use, none of my finer nibs caught on the texture. Zarazara would be good for someone who enjoys paper like MD Cotton and prefers more tooth to their paper.

The Perpanep notebooks are available for $14.25 each from JetPens, who provided these notebooks for review.

Kokuyo Enpitsu Sharp 1.3mm Mechanical Pencil Review

(Jeff Abbott is a regular contributor at The Pen Addict. You can find more from Jeff online at Draft Evolution and Twitter.)

Before seeing the Enpitsu Sharp 1.3mm mechanical pencil from Kokuyo, I don't think I really knew that they made anything besides paper products. I really enjoy their paper, and I really can't pass up anything that comes in a bright, semi-transparent color, so this mechanical pencil was an instant want. I'm not even sure I noticed the lead size until I had the pencil in hand — that's how much I love anything that features a bright, semi-transparent color. To sum it up, the wide lead took some getting used to, but after settling in, this is a really comfortable and fun pencil.

Let's talk about my favorite part first — the color. Described as a yellow-green, this bright neon material is so good. It's slightly transparent and frosty so that you can see the components under the pencil barrel in blurry detail. It brings back memories of lots of different items I enjoyed in the 90s that took advantage of the bright, translucent plastic aesthetic of the time. I'll pretty much always pick something in this aesthetic over other options, and it's especially problematic if something is offered in multiple bright/translucent color options. For this pencil, it's quite simple — if you look at it and smile, then it will fit you perfectly. If you think it's garish or loud, then that's fine too — there are so many good pencils out there that will have a color option you love.

Due to the bright color, it can be a bit difficult to discern the slight triangular shape of the barrel, but it's there. Even though it's hard to see, your fingers can immediately sense the petit, soft corners that make up the three sides of the pencil grip. It's really well done and offers a bit more grip than a plain round barrel. For my grip, it feels fantastic when writing. On top of that, the barrel material feels almost porous. It's not soft-touch plastic, but it has a similar feel. Whatever it is, it provides great tactile feel and doesn't slip.

Something else that fascinated me about this pencil when I first looked it over is that there isn't a cap or eraser on the tail end of the pencil. Yes, it uses a click mechanism to advance the lead, but there aren't any removable parts or an eraser. Instead, there's a hole in the click mechanism that is just a hair larger than the 1.3mm lead that you can insert. Once you insert some lead, it feels like there's a gentle clutch that prevents the lead from coming back out, and I had zero success in trying to shake the lead out of the open hole in the pencil. Even if the stars aligned and the lead found the perfect trajectory to the hole, the small clutch mechanism would prevent it from actually escaping. I'm still fascinated by this odd design choice every time I pick up this pencil, and that's one of the reasons that I keep picking it up.

Getting to what I think is Kokuyo's main selling point for this pencil — the 1.3mm lead is wide. As someone who rarely uses 0.7mm lead because it feels too wide, this was a bit of a struggle to get used to. On top of the width, this lead is also extremely soft, so it wears down very quickly. If you're writing, your fingers will get a small workout as they continuously have to rotate the pencil to keep a usable edge against the paper. But, if you want a large writing surface for shading, hatching, or anything else that requires lots of dark graphite, this lead size and softness makes that an easy task. After getting used to the diameter of the line, I really have come to enjoy the dark, rich line that this lead produces. It's similar to writing with a wide rollerball refill that makes dark, crisp lines on the page. It's not my everyday preference, but I can certainly appreciate and enjoy it.

I really wasn't sure what to expect from this pencil. As I've stated too many times already, I only got it because of the color — and even if I never used the pencil, I'd still be happy to have it just as a decoration to look at. But I've been pleasantly enamored with the wide, rich lead and the quirky refill system that I keep reaching for this pencil over other pencils or even pens.

At $6, it's also an incredible value — especially if you know that you can really benefit from the wide lead option. For most mechanical pencils, 0.7 is the largest "easy to find" option, and 1.0mm can be had in limited supply. Anything bigger usually comes from a lead holder, but they're not as easy to use as a simple mechanical pencil. Again, this all comes down to how you intend to use a pencil or what you need from it. All I can say is that this $6 pencil has provided me with a lot more joy than I ever expected.
