Metal detectable permanent markers let you label cases, bags, containers and equipment without the marker or its cap becoming a foreign material risk. Choose the V2.0 retractable permanent marker in bullet (2.0mm) or fine (1.0mm) tip, with a spring-free mechanism and no cap to lose, the pocket-sized compact retractable permanent marker, or the capped detectable permanent marker, whose cap is as detectable as the body. For bold marks readable across a warehouse, the aluminum jumbo marker has a 1" nib, and the F700 felt tip pen suits labels and charts. Most come in black, blue, red and green. Need erasable ink?
