Tomoe River paper by Sanzen (Sakae Technical Paper) is world-renowned for its ultra-thin yet durable design, loved by fountain pen enthusiasts for its exceptional writing experience. This A5 hardcover notebook contains 184 sheets (368 pages) of 52 gsm dotted paper—perfect for long-form writing, journaling, or creative projects.

Fountain pen friendly, it resists feathering and bleed-through while beautifully showcasing ink sheen and shading. Ghosting (show-through) is expected due to its thinness, but many writers embrace this as part of the Tomoe River experience. The silky smooth paper surface ensures crisp lines and rich color expression, while the clear protective cover keeps your notebook safe.
