Cosmo Air Light Paper

This is a 75 gsm Japanese paper. It has been on the agenda of the fountain pen world (and our's) for a while. This is the most sheen and shading we have ever seen. Here's a detailed review of the CAL paper.

Feedback is available while writing, as its surface is not as covered as the Tomoe river, Rhodia, etc. The paper isn’t slick like Tomoe River either. Instead, it has just enough texture that you don’t feel like your pen is ice-skating over the surface. But still, it provides a smooth writing experience. Your text is a click thicker but there's no bleeding and minimal ghosting. The colors are very vibrant. The drying time is a bit longer. I personally think it's especially suitable for applications such as a journal, watercolor, etc.

Here's the pictures and a quick video review:

Gorgeous notebook

The quality of this notebook is fantastic. The paper is beautifully smooth and a joy to write on. The presentation with the magnetic case, guides and leather blotter just make it a great purchase.

Different than Tomoe River, but not worse

I’d have to say Tomoe River feels a little better than the Cosmo air, but only marginally. This also is purely personal preference. I do prefer Cosmo over Midori paper which I’ve been using for years. The Cosmo is slightly thicker than TR and that’s a good thing “in my book” (pun intended) ink does not show through Cosmo as much as TR. TR is great, but for the price (and availability) Cosmo Air is a great substitute

Ornate magnetic case, lovely sheen, pages open flat!

I am still new to the fountain pen world and this is my first serious notebook purchase and boy I am not dis-appointed. The notebook and case has a lovely maroon cover, beautiful lettering and shouts class!
The note book has a good thickness which the pages has a nice off white colour. The thickness of the pages is very good which lay FLAT and has no bleed through. The paper shows the sheen in ink very well. This is the first time I have received a leather blotter and the inlay cards are great.

Everyday notebook A5

So thrilled to find that Galen is now offering this notebook in Cosmo Air Light Paper! I love that they changed the cover color to a beautiful burgundy! Beautifully packaged and shipping is always fast! Thank you Galen Leather for another wonderful product!

Excellent notebook with exceedingly great value!

This notebook is astounding. It shows off ink better than Tomoe River in my opinion, is incapable of feathering, shows sheen like no other, and has a great soft feel but not a slippery slope like Tomoe. Both Galen notebooks are amazing I was simply shocked by the quality and performance. This is a must have notebook in your collection! Hoping to see a leather variant soon :)

Vlade Malfet (New Grant, TT)
Everything you see is true.

This paper brings out the ink beautifully. It is very smooth to write on. I have no regrets in buying this. The burgundy color compliments journals nicely.

Chris OKeeffe (Guernsey, GG)
Lovely paper

This paper is very different from tomoe river, but in a good way. It has a completely different feel to TR 52 or 68. It is very ink friendly and shows off the properties of each ink very well.

Steve (San Marino, US)
Sturdy, quality notebook with great paper

I love Tomoe River but sometimes I want to be able to write on the backside of pages without the distracting ghosting. The cosmo air paper does a great job overall, especially showing off sheening inks very well, and both sides of the page are easily usable. The quality of the construction of the notebook itself feels sturdy and great in the hand, and the packaging is first class all the way.

Francisco Bermudez (San Juan, PR)
Surprised with what I saw

I could not believe what I saw with the writing samples of the inks that I have. I expected good beautiful result with the J. Herbin Emerald de Chivor because this is how the notebook is advertised to do well when using inks with sheen/shimmering. The surprise was that not only the Emerald of Chivor showed this effects beautifully but also saw the effect on inks that are not advertised as having sheen and/or shimmering. Saw gold shimmering in the Lamy Crystal Topaz, silver shimmering in Montblanc Irish Green, gold shimmering in Montblanc Encre du Dessert, red sheen in Noodler's 54th Massachusetts, as well the red sheen and gold shimmering of the J. Herbin. The feel is super smooth, ghosting is neglible, barely there, no bleed through. Overall, with the box where it comes and the blotter and guides included, I don't think you can have a better notebook.

Jeremy Williams (Sierra Vista, US)
Great paper, great sheen, great shimmer, long dry times

Seriously, I have used quite a bit of (second gen) Tomoe River paper, Rhodia, Midori. Clairefontaine, and piles of generic printer paper. This stuff seems to sheen/shimmer at least as well, some inks even better. The only drawback is the dry times. Unless you’re writing in full sun, it’s going to take a while to dry, use the blotter it comes with or you’ll end up wearing a lot of extra ink you weren’t planning on. If you select a supremely wet or messy ink, it compounds that problem. OS Nitrogen, J Herbin Perle Noire, Noodler’s Navajo Turquoise and a couple others just don’t ever seem to dry without the blotter. You won’t be disappointed with the paper quality as long as you follow that tip.
On a scale of 1 (none) to 3 (average) to 5 (lots):
Feathering: 1
Bleed through: 1
Ghosting: 3
Toothiness/feedback: 2-3
Dry times: 5+
Shimmer: 5
Sheen: 5
Shading: 5
Haloing: 4
