Introducing the Uniball One with new innovative bold and bright ink. 

This pigment ink is formulated to sit on top your paper rather than absorb and disappear into the paper. 

The result is a bold bright ink that doesn't fade. 

The pen has a cool design, but its main selling point is a pigmented ink which will be sold with a set of new refills in the “UMR” family. 

The UMR refills are generally seen in Uni’s Signo pens, but to date they have been non-pigmented inks. 

The pigmented inks have darker colors and water-resistance that normal gel inks can’t match.

Uni asserts that darker colors are easier to read and create writing that is more memorable than lighter colors.
