U-Mark A20 Paint Marker with Reversible Tip carries 30% more paint than a standard A10 and gives you two line widths from a single pen — pull the tip out, flip it, and go from bullet to chisel. It runs the same Greenlabel® xylene-free liquid paint, so it clears plant VOC and solvent restrictions while still marking permanently on metal, stainless, plastic, glass and more.
Made in Belleville, Illinois, USA. Sold as a 12-count box (1 dozen) in fifteen colors.
