“The notebook fits perfectly.” Introducing “uni-ball one F” from “uni-ball one”
[High-quality shaft specifications]
It has a smooth design with minimal unevenness. The metal tip provides a stable writing feel.
[Ink using new pigments]
Unlike general gel ink, it uses a new pigment that minimizes the penetration of colorants into paper fibers. The pigment used in Uniball One Ink is a uniquely developed bead-packed pigment that confines conventional coloring materials into particles.
By trapping the pigment that serves as the coloring material in the ink inside the particles and increasing the size of the particles, we minimize the penetration of the coloring material into the paper surface. As a result, the coloring material on the paper develops its original color, and black becomes darker. You can write characters that will be memorable when you look back at your notes.
[No smearing, quick drying ink]
By changing the ratio of solid and liquid components in the ink, we are able to quickly penetrate the liquid component into the paper surface while still allowing the solid coloring material to remain on the paper surface.
Although it is a quick-drying ink that penetrates quickly into the paper surface, it prevents the coloring material from being absorbed into the paper surface, so it does not bleed or bleed through.
[Simple and straight shaft design]
The shaft design is simple and straight. The oval-shaped "Open Wire Clip" not only has a stylish design, but also has functionality as it is a movable clip that is easy to clip onto a notebook or notebook.
[Axis colors that let you feel the story]
This is a special axis color selected with the theme of "Fated Color x Casual Scenery and Colors of Everyday Life".
