Irradiated UltraFine™ Smear-Proof Markers

An irradiated permanent marker with an ultra-fine micro tip, that produces a thin and precise 0.3 mm line. The quick-dry and smear-proof ink provides the ideal marker for lab samples and slides, glass, plastic and paper substrates. Equipped with a long nib, the Ultra-Fine permanent marker easily handles writing in limited space, especially on cleanroom labels and documents. The capped marker is available in black or blue ink and holds up to frequent wipe downs with IPA, bleach and phenols.
