Kyokuto's F.O.B COOP W Ring notebook has a two-layer front cover—a translucent cover on top, and a beautiful glossy cover underneath. Both are thick and flexible. The back cover is thicker still, and less bendable. The notebook lays flat when pages are folded back, thanks to the "W" rings (twin rings). This type of binding, along with the stiff back cover, makes it easy to jot notes while holding the notebook in your hand. The paper inside is smooth, offering an enjoyable writing experience. The upper corner of every page has spaces to fill in the page number and date.
The notebook contains 80 sheets, and each page contains 31 lines of 7 mm rule. Kyokuto calls this a B5 notebook, but the actual dimensions are semi B5: 7.0 x 9.9 inches (17.9 x 25.2 cm).
