Uni-ball One F Gel Pen – 0.38 mm – Fade Pink – Black Ink

The best feature of the Uni-ball One F gel pen is the beautiful barrel. While the original Uni-ball One was only available in white barrels, this time the Uni-ball One F adds six new barrel colors to make the world vivid and refreshing in the winter of 2021! On September 21, 2021, Uni-Ball released the One F, which is basically an updated version of the original Uni-ball One gel pen. Uni-Ball One F has improved pigment ink with darker black tones and other ink colors are more vibrant. Uniball One F was also upgraded with a stabilizer mechanism and low center of gravity. The nose on the Uniball One F has also been upgraded to metal.The newly developed “uni-ball one” ink, unlike general gel ink, uses a new pigment that minimizes the penetration of coloring materials into the paper fibers. The pigment used in “Uniball One Ink” is a uniquely developed bead pack pigment in which conventional coloring materials are enclosed in particles.General quick-drying ink achieves quick-drying by speeding up the penetration of the ink into the paper surface. As a result, ink bleeding or strikethrough may occur. The newly developed “Uniball One Ink” changes the composition ratio of solid and liquid in the ink to allow the liquid components to quickly penetrate into the paper surface while leaving the coloring material, which is the solid content, on the paper surface. Even though it is a quick-drying ink that penetrates quickly into the paper surface, it does not bleed or strikethrough to prevent the color material from being absorbed into the paper surface.The body design is simple and straight. The black ink uses a black body color that emphasizes the darkness, and the color ink uses an off-white body color that blends into your living space to create a calm impression. In addition to its stylish design, the oval-shaped “Open Wire Clip” is a movable clip that can be easily inserted into a notebook or notebook, and is a specification that also has functionality.
