Uni-Ball
Uni One Gel Pen Refill - Black
$1.50
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.
SPECIFICATIONS:
- Black ink
- 0.38 mm or 0.5 mm nib
- The gel pen refill is compatible with Uni-ball One Gel Pens.
