Uni-ball Signo 307 Gel Ink Pen Review

The Uni-ball Signo 307 is an interesting pen for many reasons. To most people it's just some pen they grab off the shelf at Wal-Mart (ok, that's where I bought mine too), but for someone like me, this simple pen opens up a Pandora's box of questions.

What exactly is Uni-ball trying to do with this pen? Is this a replacement to the Signo 207, which is likely their top selling gel ink pen of all time? Or is it to sit alongside the 207 on the shelf? I'd check with Uni-ball, but the 307 is not listed on the North American site (or the Japanese site for that matter), the latest Press Room document is from 2008, and both their Twitter and Facebook feeds have not been updated since December 2013. The lack of social media updates is somewhat shocking in this day and age.

So, I'm left to do my best and answer any questions I have about this pen myself.

Is this a replacement to the Signo 207? I have to say yes. The general shape, design, and features of the pen mimic the 207, and improve the pen in some areas. Where the tip cone and clip in the 207 were metal, they are plastic in the 307. I wasn't sure how this would work, but it works well. The 307 is a quieter pen when writing than the 207 and I think the full plastic build is why. There was also a visual update on the 307, with a subtle grid gradient on the barrel. Including the black tip, the entire graphics overhaul is nice.

Ink wise, it writes wonderfully. According to the packaging, the 307 is skip-free and I found that to be the case. The 207 did have issues with skipping from time to time - the blue ink primarily in my experience - and the new models have none of that. They also feature Uni-ball's Super Ink technology, which makes the ink waterproof and fraud resistant. The new refill is marked UMR-87E, while the refill in one of my older black 0.7mm 207's is marked UMR-87. At some point in the last couple of years Uni-ball did start using Super Ink in the 207 but I'm not sure when exactly, and I'm not sure if the refill designation denotes that or not. Maybe Uni-ball can clear this...oh nevermind.

I will say that the ink color is darker in the older UMR-87 refill compared to the UMR-87E refill. It's close - close enough that 99% of users wouldn't notice - but I do see a slight difference when the ink dries.

What happens next with the 307 will determine the future of this pen. Will it be available in different tip sizes such as 0.38 mm, 0.5 mm, and 1.0 mm like the 207? How about the rainbow of colors offered previously? Will the BLX line convert over to the 307 as well? I would like all of those things to happen personally. The 307 is a very good pen and an upgrade to the 207. Maybe Uni-ball will let us know one day. Or, maybe it will just show up at Wal-Mart.

Retro 51 Tornado Vintage Metalsmith Juliet Heart Tree Rollerball Pen Review

(Susan M. Pigott is a fountain pen collector, pen and paperholic, photographer, and professor. You can find more from Susan on her blog Scribalishess.)

The Retro 51 Tornado Vintage Metalsmith Juliet Heart Tree Rollerball Pen (what a mouthful!) is a design created with acid etching and vintage metal accents. The Juliet looks like tree bark, and, because the design is etched, you can feel the texture with your fingers.

A heart with an arrow appears below the clip, and it just begs for initials. I asked, but you can't get that part of the pen engraved. I suppose you could write initials on the pen yourself using a Sharpie or other permanent marker to personalize it.

The Retro 51 Tornado is substantive for an average-sized pen. I couldn't find any specifications regarding its length, width, or weight, so I took my own measurements. Length without point extended: 12.5mm; Length with point extended: 12.9mm; Width at clip end about 1.8mm; Width at top of cone about 1mm; Weight: 1 ounce [29.57 ml] (if my scale is at all accurate).

The pen balances fairly comfortably in the hand, though it tapers dramatically from the clip end to the cone. If you like thick grips, this pen may not be comfortable for you. I wrote with my fingers on the cone, though you could hold the pen further back for a slightly wider grip.

The rollerball ink flows smoothly and didn't stutter or leave ink globs on the paper. I was pleased with how beautifully the pen wrote.

The pen comes with a Retro 51 Tornado rollerball refill. The Goldspot website doesn't state what size the rollerball is, but it feels like a medium (0.7) to me. Apparently refills from other brands (Monteverde, Schmidt, and Parker) can be used in the Retro Tornado pens, and you can choose either rollerball or ballpoint refills. These come in sizes other than medium.

The retractable rollerball system works smoothly. Turn the knob clockwise to extend the tip and counter-clockwise to retract it.

The clip is rigid. I could not lift it at all. I suppose you could clip the pen to a piece of paper, but getting it over a shirt pocket might require pliers.

Refilling the pen is simple. Just unscrew the cone, remove the spring, insert the new refill, replace the spring and cone, and you're done. I noticed while writing that the spring or pen cartridge knocks against the cone making a constant clicking noise. I tried replacing the spring and pen cartridge several times to see if repositioning it helped. It didn't. It's not terribly noisy, but if clicking noises bother you, be forewarned that this pen clicks.

I like the design of this pen, though I would have chosen brown for the etched portions to make it look more like a tree. The heart and arrow in a different color (maybe in red?) would have added to the playfulness of the design. Unfortunately, a visible seam runs along the length of the pen, and it looks unprofessional.

After writing several pages with the Retro Tornado, my hand got fatigued. The pen is fairly heavy and the steep taper forces your fingers into an uncomfortable writing position. Although Retro 51 offers many fun designs (I particularly like the Albert which sports a black background and mathematical equations), this is not a pen I would purchase for myself. The weight, the steep taper, and the clicking noises didn't impress me.

However, for people who enjoy quirky designs and solidly-built rollerballs, the Retro 51 Tornado is a good choice for short writing sessions. The Juliet version is currently on sale at Goldspot Pens for $28.00 (regularly $35.00). Refills are $4.00 a piece. Be sure to check out the Albert ($40.00) and all the other Retro 51 designs. I was sorely tempted to buy a Harley Davidson Blackline Skull Pen ($65.00) because who doesn't want a skull pen? Right?

Sakura Ballsign Knock Gel Ink Pen Review

When I think Sakura, I think of only one pen: The Sakura Pigma Micron. This art/drawing/sketch pen is ubiquitous, appearing in creators pen stashes all over the world. Sakura makes other pens too, like the Grosso that I was a fan of back in the day, with the Sakura Ballsign Knock Gel the most recent to land on my desk.

The Ballsign is your basic entry level micro tip gel ink pen. Simple plastic construction, lightweight, knock retractable mechanism, 0.4 mm conical tip - pretty much how you would draw it up. One addition on the Ballsign is the presence of an elastomer grip, which is essentailly a grippy overlay that works surprisingly well. I actually didn't notice it at first. I thought it was just the standard plastic barrel continued through the grip, but I realized soon my fingers weren't slipping at all and the elastomer grip was why.

When writing, the Ballsign feels a lot like its competition. The lines are solid and sharp, although oddly enough I felt the orange lines were cleaner than the blue black. The colors look spot on too, at least on the two of the 15 colors I tried out. Another interesting takeaway is that the Ballsign refills match the shape and design of the Uni-ball RT1, so it could fit in those barrels that use RT, 207, and Jetstream refills if you are so inclined.

The Ballsign is not a world beater, but it is a solid option in the world of micro gel ink pens. For me, they rank lower than the Uni-ball Signo DX, RT1, and 207, as well as the Zebra Sarasa Clip and Pilot Juice. It falls in the Pentel Slicci/Muji Gel range, which is a good spot to be. Give them a shot, especially if you want to try some of the more interesting colors like brown black, red orange, and cherry pink.
