The Yamamoto Paper Cosmo Air Light is known for its ability to make inks look their best, but every time I use it, I'm surprised at how well it works. Inks stand out so well on this paper that it makes me want to keep writing, even when I've run out of things to write.

This notebook from Yamamoto packages that experience in a nice, no-fuss minimalist book that ticks all of the boxes for a paper enthusiast.

The cover is a plain, grey cardstock that is flexible but sturdy enough to be a writing surface when needed. It's begging to be decorated with stickers, washi, or your own artwork. The spine is bound with a fabric tape with a minimalist brand stamped into the fibers. The sewn binding allows it to lay flat after a bit of training.

Insisde there are cardstock endpapers, and then 176 pages of excellent plain paper. There are no lines or words or numbers--it's just an open world of possibility. There is a line guide sheet included, which offers a 6mm grid or 12mm line if held behind the page you're using. This way, every page can be exactly the format you need, whether you're sketching, writing, or taking notes.

The paper is what really makes this notebook. Not everyone likes the texture of Cosmo Air Light (Brad), but there's no denying the way it makes ink stand out. If you want to show off shading or sheen, this is the best option out there, in my opinion. The cushy texture of the page is exacerbated by fine point pens, but medium and broad tips glide over it with no problem at all, which are generally what one uses when showing off ink properties, anyway. It also works fabulously with pencil, ballpoint, rollerball, gel, fineliners, even Sharpie--pretty much anything you want to write with. It's a finer, 83gsm paper, so there is ghosting, but not even the Sharpie bled through--not even a dot. The paper does have a long dry time, though, so patience or a sheet of blotting paper are required.

I've really enjoyed using this notebook. There's nothing extra about it--it's just a plain cover holding together a generous chunk of very nice paper. It's not too "nice" to use. The minimalism is inviting and utilitarian, and I find I keep reaching for it.

It's not inexpensive at $21, especially for a softcover notebook. But you do get a good page count for that price, so I don't think it's asking too much. There are certainly less expensive notebooks with paper that is almost as good, but the emphasis is on "almost." This is paper for ink lovers. Ink lovers with lots of writing to do.

Pebble Stationery Cosmo Air Light x Liberty London Notebook Review

(Sarah Read is an author, editor, yarn artist, and pen/paper/ink addict. You can find more about her at her website and on Twitter. And check out her latest book, Out of Water, now available where books are sold!)

I'm not sure I've ever called 'dibs' on a review item as quickly as I did for the Pebble Stationery Cosmo Air Light x Liberty London Notebook. Aesthetically, this notebook was a win for me even though I'd not yet tried Cosmo Air Light paper, of which I've heard mixed things. I was very excited to try it for myself.

Liberty London William Morris designs get me every time and this design is completely gorgeous. Pebble Stationery has several other Liberty London designs as well, but they are fairly limited, so if you're as stricken as I was, act quickly!

This notebook is an A5 hardcover wrapped in fabric. It is entirely handmade, so each one is slightly unique. The binding is sewn stitch and it includes a satin ribbon bookmark that coordinates with the fabric color. The binding does allow the notebook to lie open flat, with some training. Between those stunning covers are 160 pages of blank, 75 gsm Cosmo Air Light paper. Which I now know I like very much.

I have been told I would love CAL paper, but I've also been told I would hate it, so I really wasn't sure what to expect. It definitely has a unique texture to it, somehow both smooth and grippy at the same time, which makes no sense unless you've used it. It's smooth, but has drag. I found it pleasant to write on. I saw beautiful shading, lovely sheening, and no feathering or bleeding. Even the Sharpie did not bleed through, which shocked me. So I got a bigger Sharpie and tried that, and it still did not bleed through. The only bleeding I got at all was when I poured ink onto the page and let it dry. Impressive.

The only negative issue I had with the paper at all was that it has a very long dry time, similar to most coated papers. It's not an issue that bothers me much, but I know it can be a problem for some, especially lefties.

Overall, I think this is a very nice notebook. It's well constructed with that special handmade feel, with top-notch materials. And somehow, even with all that considered, it's only $28. I was genuinely shocked by that price, but in a good way. It could easily have been half again as much and still reasonable, especially for a limited run. You should probably get one or three before they read this and come to their senses.

Musubi Cosmo Air Light Folio Notebook (A5): A Review

Musubi Cosmo Air Light Folio Notebook Review

The Musubi Cosmo Air Light Folio Notebook is a beautiful minimalist notebook with 208 pages of Cosmo Air Light paper. Simple white cotton adorns the cardstock covers of the notebook. The cotton has a lovely texture to it, and the only branding is the barely-visible Musubi logo embossed on the bottom right corner.

The end pages are made of a thicker, water-color-like paper. There's no printing, branding, or decoration whatsoever. The outside corners of the notebook are rounded.

Inside, the pages are Smyth-sewn, so they lie completely flat when the book is open. Cosmo Air Light is 83gsm, so it is thicker than Tomoe River Paper, but lighter than Bank Paper. My notebook is the lined version. The lines are printed in a light sage ink and are spaced 7mm apart. In addition, there are small marks at the top and bottom of each page which divide the page up into halves, thirds, and fourths.

I first discovered Cosmo Air Light paper when I did a review of the Yamamoto Fountain Pen Friendly Paper Collection (part 1 and part 2). It was one of my favorites in the collection.

The paper is smooth and lacks any texture. Its smoothness derives from a coating that is put on the paper (originally for book printing). The coating enhances any ink's sheen or shading properties. The thickness of the paper means that there's very little ghosting and no bleed through, which makes Cosmo Air Light more user friendly, in my opinion, than the popular Tomoe River Paper.

I tested the paper with eleven fountain pens with varying nib sizes and different inks. The paper handled all the inks with ease--no feathering, no bleeding, and only slight ghosting (so little it doesn't show up in photos). Several inks shaded well, and sheen was evident in Iroshizuku Take-Sumi, Robert Oster Tranquility, and Iroshizuku Yama-Budo. The only negative was a lengthy dry time for the wetter inks.

Swabs on this paper look fantastic. The ink colors are vibrant and true, and shading and sheen are pronounced. On the reverse side there's no bleed through and only mild ghosting.

I tested the paper with a dip calligraphy pen inked with Taccia Sabimidori (reviewed here). I discovered that Cosmo Air Light is not the best paper for calligraphy. Because of the coating, the ink does not settle into the paper well, resulting in thick lines and uneven lettering. Compared with Ayush Paper (reviewed here), Ayush wins hands down for calligraphy--the paper absorbs the ink more quickly, allowing for good results with flex. Although the ink doesn't sheen as much as Cosmo Air Light, I think the trade-off is worth it if you're doing calligraphy.

I did longer writing samples with three pens: a Santini stub (reviewed here), inked with Robert Oster Tranquility; a Lamy 2000 fine, inked with Iroshizuku Take-sumi; and a Leonardo stub (reviewed here), inked with Monteverde Mulberry Noir. Cosmo Air Light really shines as a journaling paper because it handles different pens and inks so well. There's a pleasant sensation as you write on this smooth paper. Once again, I noted no feathering or bleed-through and only slight ghosting.

Cosmo Air Light remains one of my favorite papers. It outshines Tomoe River Paper in many ways: it is thicker and therefore does not suffer from ghosting; it has a smooth surface and is pleasant to write on, much like Tomoe; and it enhances sheen and shading even better than Tomoe (although that can mean longer dry times). I realize that one of the things people (me included) love about Tomoe River Paper is how thin and light it is. That's a great quality for planners, because it keeps them thinner overall. But for journaling, I think Cosmo Air Light is a better choice because you can write front and back without your writing showing through.

The Musubi Cosmo Air Light Folio Notebook retails for approximately $25.00 (35 Singapore dollars). You can get it with plain pages, lined pages, or cross grid with page numbers. It doesn't have many bells and whistles--no ribbon bookmark or pockets or elastic closure, but I love its minimalist design. I've never seen a notebook with so little branding. It's elegant, beautiful, and functional. And, sometime in 2021, Musubi is planning to release covers for their Folio Notebooks in the beautiful materials they use for their handmade notebooks. I can hardly wait!
