UNI-BALL ONE P 0.5MM

The Uni-Ball One P 0.5MM is a gel pen that is shorter than a regular pen, making it easy to carry in your pocket. It has a 0.5mm conical rollerball nib and a special formulation of ink that uses large pigment particles that sit on top of the paper, making the ink color particularly vibrant. It also has waterproof ink that guarantees vibrant writing that won't bleed.
