Great value! Set of 8 Uni Pin fineliners with black ink. Top sizes (mm): 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8. Ultra fine markers with smooth flowing ink that features superior water resistance, so once it dries, the ink will not smear, even if water is spilt on the page. Being light resistant makes the Pin a great art tool as work can be displayed and will not fade even under continuous exposure to light. Permanent on paper.
