Bullet Jotter Writing Pad Refill – Canopus

If you already own a Bullet Jotter Writing Pad & Cover Set and want to write on paper engineered for precision and speed, this Japanese writing pad refill is the upgrade—Canopus by Yamamoto Paper, a micro-coated 65 gsm sheet that delivers glass-smooth strokes in Bible size (3.7" × 6.7"), ready to slot straight into your cover.

Canopus was developed as Yamamoto Paper's answer to the demand for a fast-drying, ultra-smooth paper after the discontinuation of Cosmo Air Light. The micro-coating on the surface creates a sealed layer that dramatically reduces dry time for fountain pen ink while preserving the full character of each ink—its color, saturation, and any sheen it carries. At 65 gsm, the sheet is substantial enough to handle confident strokes while remaining light enough to use both sides without significant bleed-through.

Fountain pen ink dries faster on Canopus than on most uncoated papers, which significantly reduces smearing for left- and right-hand writers alike. Lines stay sharp and defined, with excellent color payoff and strong sheen on saturated inks. The smooth surface also makes Canopus a natural choice for ballpoint and gel pens—reduced drag translates to noticeably more comfortable long writing sessions—making this Japanese loose leaf paper as practical for daily journaling as it is for fountain pen enthusiasts.

Yamamoto Paper — Preserving the Joy of Paper for the Future

Based in Sakai, Osaka, Yamamoto Paper was founded in 1972 as a paper specialist. Drawing on decades of experience connecting paper manufacturers with end users, they now design and produce their own original stationery. At the heart of their work is a belief in "sharing the joy and warmth of paper with confidence for generations to come."

Rather than simply selling beautiful paper, Yamamoto Paper values delivering the full character of each sheet—its writing feel, texture, and the way it changes over time. They are also known as "custodians" of paper culture, reviving legendary papers that have gone out of production and passing them on to the next generation. What makes Yamamoto Paper especially beloved is their balance of craftsmanship and playfulness. Their Paper Tasting series, for example, lets you sample different types of paper as if you were tasting wine, turning the exploration of paper into a delightful experience. It's this combination of uncompromising quality and creative spirit that has earned them loyal fans among stationery lovers and fountain pen enthusiasts around the world.
