uni-ball one F

The "uni-ball one" series is a gel ink ballpoint pen that develops darker black and more vivid colors. In addition to the simple axis design, it features a world view such as the theme of each series, a package design that shines on SNS, and an impressive ink color name.



The new series "uni-ball one F" features a thematic axis color, a low center of gravity, and a stable writing taste. The shaft color is based on the dull color that is becoming established in miscellaneous goods and daily necessities, but is finished in a faded color that makes you feel the passage of time. When selecting colors, pay attention to the casual scenery that you see in your daily life so that the user can sympathize with your emotional sensibilities. The design of the entire shaft has a smooth form with as few irregularities as possible, and one point of the metal parts at the tip emphasizes simplicity and leaves a sophisticated impression.









The metal parts of the pen tip are not only stylish in appearance, but also equipped with a "stabilizer mechanism" that creates a stable writing taste with a low center of gravity. It is said that it will be possible to write "dark and clear" black ink, which is the biggest feature of "uni-ball one", more stably and smoothly with a light force.
