Tomoe River paper by Sanzen (Sakae Technical Paper) is world-renowned for its ultra-thin yet durable design, beloved by fountain pen users for its exceptional writing experience. This A5 softcover notebook includes 160 pages of 52 gsm grid paper, bound in a sleek black cover.

Fountain pen friendly, it prevents feathering and bleed-through while highlighting ink sheen and shading beautifully. Ghosting (show-through) is expected due to its thinness, but the silky smooth surface rewards writers with crisp lines and rich color expression. Perfect for note-taking, journaling, or sketching with ink.
