almost there!

Love the cover, love the thickness - perfect for individual writing/experimenting projects. But the paper is just too thin. I like writing with gel pens, and the bleed-through and shadowing is just not good. I pay to be able to write on both sheets of the paper. And one of the reasons I still handwrite is because I like the experience of writing out equations, proofs, observations, measurements, etc. If my gel pens are bleeding through, there is no way I would be able to use my fountain pens which hold my waterproof/water resistant inks - something critical when working around liquids. Suggestion: Work with Tomoe River Paper out of Japan. They have the same commitment to the environment that you do AND you won't have to compromise on sheet thickness. Even their 52gsm does amazing with my fountain pens, and they're a dream with my gel pens. This type of paper is what I expect when I am paying so much for a soft cover notebook. maybe also look at what Underbelly is doing with their notebooks? I got one of theirs when my little brother got one in a free treat bag at one of their tables. I was pleasantly surprised at how well it took my fountain pen ink with no shadowing, ghosting, or bleed-through. I want to be able to say that about Cognitive Surplus notebooks.

Makes a great gift!

Bought this notebook as a gift, and I was really impressed with the packaging, and the product. The notebook itself feels like great quality, and it has such a unique design.

It's Amazing!

The paper is incredible, almost nothing bleeds through, including watercolor somehow.
