Gel Pen Refills

Gel pen refills use a water-based ink which contains a thickening agent allowing a heavier pigment to be held in suspension. The resulting ink is more opaque and show up better than other water based inks on darker surfaces. Gel pens put down ink at a greater rate than rollerball or ballpoint pens. The Gel pen refills below are a standard shape to fit a large number of different pens.
