Mitsubishi Pencil Uni-ball ONE P Bath Bomb Gel Pen – 0.38mm Limited Edition

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.
