The 0.5mm edition of the Uni-ball One P comes in two colours that feel like they belong together: Banana, which is soft and warm, and Grape, which is quiet and cool. Both use the same deeply pigmented water-based gel ink as the rest of the One P range — vivid, fast-drying, and formulated to sit on the surface of the paper rather than being absorbed into it, which keeps the colour clear and the line sharp at 0.5mm. The short, wide barrel fits naturally in the hand and slips easily into a notebook cover or pencil case pocket.
