Uni Pin Fine Line drawing pens are an ultra fine marker with superior water resistance that is so good once the ink is dry it will not smear even if water is accidently spilt on the page. The ink in the Uni Pin fine line markers is extremely light resistant and does not fade even with continuous exposure to light.

Uni Pin ultra fine markers are ideal where high precision is required for example in technical drawing, stencilling & sketching. Made from polyacetal the nib in Uni Pin fine-liner pens is supported in steel and there is a choice of 7 line widths and also 3 ink colours.
