The Edding 751-006 is an industrial strength, permanent marker ideal for industrial marking, MRO, electrical, production and assembly line marking applications. The marker features a valve-controlled ink flow and a felt tip of either 4.0mm or 5.6mm which reduces blotching and smudging, even on non-absorbent surfaces. The ink is low-odor and lightfast, and is resistant to water, grease and chemicals. The 751-006 is available in black, blue, red and silver colors.
