Uni-ball ONE F Gel Pen

[Description]

High Color Development - Darker and More Vivid

The newly developed Uni-ball ONE ink stands out from regular gel ink by offering exceptional color richness, resulting in deeper blacks and more vivid colors.

This is achieved by developing a new type of pigment, BEADS-PACK pigments, that trap and confine colorant material into particulars and increase the size of these particulars, thus effectively minimizing the paper's absorption of the colorants. Since more pigment particulars stay on the paper's surface, it enhances the intensity of both black and colored inks.

Beyond making writing clearer and neater, experiments conducted in collaboration with Ritsumeikan University's College of Comprehensive Psychology found that darker ink may help improve memory of the written content.

Non-Bleeding & Quick-Drying

Despite more colorant remaining on the paper's surface, Uni-ball One ink dries quickly and does not bleed through. This is achieved by adjusting the ratio of solids to liquids in the ink, allowing the liquid to be rapidly absorbed by the paper for quick drying. The colorant materials, as mentioned, stay on the surface due to their larger particle size, thus preventing bleeding.

Japanese Aesthetics: Poetic Colors Derived from Nature

The entire series offers seven different barrel colors, with four available in 0.38mm and five in 0.5mm. Each color is inspired by natural objects and landscapes, each given a poetic name with elements of Japanese culture, evoking your feelings towards nature when writing.
