The COSMO NOTE A5 Notebook won THE BEST PAPER of "Find Your Fountain Pen Friendly Paper" in 2019 San Francisco Pen Show. The Cosmo Air Light paper was evaluated with "beautiful sheading" and "sheening" of fountain pen ink. It is 20% lighter than matte corted paper regardless of the same thickness. The team has chosen 83gsm as the paper weight because of its writing feeling and condition of seeing through the guide sheet.
COSMO NOTE has 176 plain pages, and it comes with a 6 mm squared /12 mm lined guide sheet. Section-sewn binding is used to produce this notebook to give extra strength and durability. You can open it 180 degrees flat, or fold it 360 degrees.

The Yamamoto Paper's team took 6 months to design the COSMO NOTE. They were conscious of a simple, universal design that would live up to the name "COSMO," which means the universe harmony. The cover is made of Colorplan Smoke by G.F Smith of England, which has a rich material feel and a calm and quiet atmosphere.
Instead of using vinyl cloth, tjhey expressed environmental awareness and innocence by showing a plain weave cloth woven with warp and weft yarns alternately rising and falling, and paper-lined cold gauze as a finishing touch. The gold leaf COSMO NOTE on the gauze looks like a newborn star. For the reverse side, they used special Tokai Paper Mills Tanto Select, which has a gentle off-white color that stimulates the senses and welcomes the viewer into the world of creativity.
