LABELING
The marking pens write cleanly and crisply on PFA without beading or smudging. Excellent for identifying or numbering PFA containers or other labware. Note: soaking marked items in acid or boiling water is not recommended and will likely remove the marks. Easily removed with acetone or IPA. Available in red or black. Sold in quantities of 10 per box. Manufactured by Staedtler.
