Description

Two of Mitsubishi's quietest triumphs, packaged together. The Uni-ball One P — the pocket-sized, short-and-stout evolution of the cult uni-ball One gel pen — arrives in an exclusive "G Irogami" barrel, its translucent body scattered with flecks of glitter and colour like confetti caught in resin. Inside, a ZENTO 0.38mm refill replaces the standard One ink, letting the pen glide with the softer, lower-friction feel that has quickly made the ZENTO line a writer's favourite.

The One P measures just 117mm — short enough to tuck into a notebook elastic, shirt pocket, or the smallest pen loop — but its slightly plumper 12.8mm grip keeps it comfortable for proper writing rather than mere jotting. The G Irogami finish sits between stationery and small object of affection, and because ZENTO refills are cross-compatible with the One family, you can keep the pen going long past the first cartridge. Uni includes a protective pipe in the packaging for safe storage of a part-used refill between writing sessions — a nice touch that acknowledges how people actually use their pens.

Clever Details That Count

  • One P Pocket Form, ZENTO Feel: The short, plumper barrel sits naturally in the hand without feeling stubby, and the ZENTO ink lays down a softer, lower-friction line than the standard One ink it replaces.
  • G Irogami Barrel: Translucent with glitter-flecked colour confetti — the "G" is quite literally for Glitter. Each barrel's pattern is slightly its own, so no two pens look identical.
  • Refill-Ready by Design: The included ZENTO 0.38 refill keeps you going well past the pre-installed cartridge, and a protective storage pipe lets you park a part-used refill without ink drying out.
