Uni UMR-38S Gel Pen Refill for Uni One Gel Pen - Blue - 0.38 mm

Description

Uni UMR-38S gel pen ink applies the newly developed “Uni-ball One” ink. The pigment in “Uni-ball One” ink minimizes the penetration of the ink into paper fibre. As a result, it develops original colours on paper, showing a darker black than an ordinary black ink pen, and showing more vivid colours than other coloured ink pens.

The gel pen refill is compatible withUni-ball One Gel Pens – 0.38 mm.
