Tomoe River FP Center Sewn Notebook A5

Tomoe River FP is a premium, 52 gsm writing paper made for fountain pen users, known for its ultra-smooth texture and ability to handle a variety of inks without bleeding or feathering.

Despite being very thin—about half the thickness of copy paper—it resists bleed-through, allowing users to see beautiful ink colours and effects like sheen and shimmer with minimal ghosting (show-through).

The paper is made in Japan, now by a company called SANZEN, which has continued the high-quality production of the original Tomoe River paper.
