- The Achiever’s Pen - There is a research result of the College of Psychology that a dark ink improves memory. Uni-ball one ink is darker and more vivid than general gel ink.
- Stain-free - Uni-ball one’s ink is firm and dries quickly so it won’t get dirty on your hands. Because it is a quick-drying ink that penetrates quickly into the paper surface, it does not smear and does not show through.
- Uni-ball one refills can also be used with Uni-ball one F. (The default ink color of Uni-ball one F is all black.) You can enjoy it by adding refills of colors other than black.
- Stylish yet sturdy - No you don’t need to use that old fashioned pen just because of its claims. Get a classic yet amazing pen today. Uni-ball one F has a fashionable silver clip, and the body is faded color, which is beautiful. Simple, straight, faded color, very nice...! You can’t go wrong if you choose this pen.
