The Uni-ball One F is what you get when Mitsubishi Pencil takes the already excellent One ink formula and puts it into an upgraded body designed for longer, more comfortable writing sessions. The barrel is wider than the original One with a lower centre of gravity, which makes the pen feel steadier in the hand and reduces fatigue during extended journaling or note-taking. The metal-reinforced tip provides a more precise writing feel at the 0.38mm point, and the One F ink uses the same BEADS-PACK pigment technology as the original One — large particles that sit on the surface of the paper rather than sinking into it, producing darker, more vivid lines that dry quickly and resist bleeding. Available in Faded Pink, Faded Yellow, and Faded Black, all writing in black ink.
