Enjoy vibrant, easy-to-read notes with the Uni-ball One gel pen. Its ink is specially formulated with large pigment particles that stay on the surface of the paper instead of getting absorbed into it. Since the ink isn't getting washed out by the paper, dark inks look darker, and bright inks look brighter. The ink is fast drying and bleed resistant, so your notes will always be crisp and free of smudges.
Compared to the original Uni-ball One, the Uni-ball One F features a wider barrel and a lower center of gravity, making it more comfortable to use for long writing sessions. This Earth Texture Color Series pen has a speckled color inspired by nature.
