The Uni-ball One F is the elevated version of the Uniball One gel pen — made for those who want their everyday tools to feel a little more considered. With a softly weighted metal tip and low center of gravity, the One F is designed for smoother lines, reduced hand fatigue, and a slightly more grounded writing experience.
It uses Uni’s signature ink, a pigment-based formula that sits on the surface of the paper for bold, high-contrast marks that resist bleeding and fading.
As opposed to the original Uniball One pen, this version does not have a rubber grip. It is smooth from top to bottom.
- Tip size: 0.3 or 0.5mm
- Black ink.

Made in Japan
