The Uni-ball One F Gel Pen is designed for comfortable, extended writing with crisp, high-contrast ink that stays visible on the page. Its wider barrel and lower center of gravity provide added stability, making it well suited for note-taking, studying, and long writing sessions.
Using pigment-based, water-based gel ink, this pen delivers bold lines that dry quickly and resist bleeding, smudging, and fading. Available in multiple nib sizes, the Uni-ball One F allows you to choose your preferred line weight while maintaining consistent ink performance.
