The Uni-ball ONE F series has a sleek and sophisticated look with a wider body barrel, a metal nib, and a slightly heavier weight than the Uni-ball ONE pens. The wider barrel also has a “stabilizer mechanism” (lower center of gravity), which makes this pen very comfortable for longer writing periods.

Uni-ball One inks are made with large pigment particles so that they stay on the surface of your paper instead of being absorbed into the paper. The inks look brighter and more vibrant because there is no absorption into the paper and they are also fast drying and bleed resistant (no smudges). Made in Japan.

Ink is refillable.
