A hard cover notebook suitable for fountain pens.

The paper used is Galvas COC, which has a supple feel and a firm writing experience. We focused on minimizing ink bleeding and preventing ink from bleeding through to the other side. It can be opened 180 degrees and 360 degrees without any stress, so it can be used while standing and holding it with one hand. Each book is hand-bound by a craftsman in Japan, giving it a textured finish.

The four standard colors, including the new dark green, and the milky white with rainbow foil are limited edition colors.

The main text comes in three types: 7mm ruled, 5mm grid, and plain.
