The Uni-ball One Gel Pen is designed to produce bold, high-contrast lines that stay crisp on the page. Its pigment-based, water-based gel ink sits on the surface of paper rather than absorbing into it, helping maintain clarity and legibility for notes, lists, and everyday writing.
Fast-drying and bleed-resistant, this pen supports clean writing with minimal smudging. A simple plastic barrel paired with a rubber grip offers steady control, while the retractable design makes it easy to use throughout the day.
