Bullet Jotter Writing Pad Refill – Sanzen Tomoe River S
If you already own a Bullet Jotter Writing Pad & Cover Set and want to keep writing on the paper that made it special, this Japanese writing pad refill delivers—Sanzen Tomoe River S, one of the most coveted fountain pen papers in the world, cut to Bible size (3.7" × 6.7") and ready to slot straight into your cover.
Tomoe River paper has a devoted following among fountain pen users for one reason: its surface lets ink behave in ways that most papers cannot match. After the original production at Tomoegawa ceased, Sanzen Paper in Kanazawa, Ishikawa Prefecture, took over the tradition in 2021. The Sanzen Tomoe River S is their current generation—still ultra-thin at 52 gsm, featherweight in the hand, but with noticeably more resilience and a subtle surface tooth that adds a tactile dimension to every stroke.
Fountain pen ink glides without resistance, delivering sharp lines, rich shading across wet strokes, and strong sheen with highly saturated inks. Bleed-through is minimal across most pen-and-ink combinations; some show-through is natural at this weight, as with all Tomoe River variants, but strokes hold clean on both sides. The paper also performs well with ballpoint and pencil, making this Japanese loose leaf paper a versatile refill across all writing tools.
