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.

Every Day Notebook

Fantastic replacement for Toemoe River paper. I use this book as an art journal and it takes heavy inking and water colour washes without bleeding.
I certainly recommend this notebook and will purchase again

My search for fountain pen paper has ended

I am thrilled with the notebook and how the paper doesn’t “bleed” through to the other side. It’s a beautiful paper and notebook!

Curiosity got the better of me…

Been a fan of Tomoe River paper so when I saw the new notebook with Cosmo Air, I figured why not. The notebook bears the hallmark of their handmade books and the paper is lovely to write on. In fact, I just purchased another as a gift!

The BEST Paper for Fountain Pens

My understanding is that this paper will be discontinued, and I'll be sad to see it go. It's a dream to write on and the best paper for fountain pens.
