The Uni-ball One Gel Pen is designed to produce crisp, high-contrast lines that remain clear on the page. Its pigment-based, water-based gel ink sits on the surface of paper rather than absorbing into it, helping preserve legibility for detailed notes, lists, and precise writing.
Fast-drying and bleed-resistant, this pen supports clean writing with minimal smudging. The lightweight plastic barrel and rubber grip provide steady control, while the retractable design makes it practical for everyday use.
