Description

If ever a pen looked as though it might fizz gently in a warm bath, this would be it. The Mitsubishi Pencil Uni-ball ONE P Bath Bomb Edition takes the beloved performance of the ONE series and wraps it in a delightfully compact, softly coloured form inspired by those swirling, speckled bath-time luxuries.

Shorter, rounder, and altogether more pocketable than its predecessors, it’s perfectly suited to smaller notebooks—passport-sized companions, for instance, or anywhere space is at a premium. Yet despite its modest stature, it writes with remarkable authority. The bold gel ink—officially recognised as one of the darkest blacks available—creates crisp, high-contrast lines that are a pleasure to read.

A cleverly engineered low centre of gravity ensures stability as you write, making this pen feel far more substantial than its charmingly compact appearance might suggest.

Why You’ll Love It:

  • Exceptionally Dark, Crisp Ink: The Uni-ball ONE ink always produces bold, high-contrast lines—so dark they’ve earned a Guinness World Record.
  • Compact Yet Perfectly Balanced: The shorter, thicker body sits comfortably in your hand and clips neatly onto smaller notebooks.
  • Playful Limited Edition Design: Inspired by bath bombs, the soft, swirling colours bring a touch of joy to even the simplest notes.

Details

  • Ball diameter: 0.38mm
  • Material: Smooth Oil-based ink
  • Country of Origin: Japan
