Needing to write on black gaff tape? The solution is a brilliant white paint marker.
Oil based permanent white markers are capable of writing on virtually any surface including rubber, wood, glass, plastic, stone and… black gaff tape. An internal, release valve in the marker channels controlled amounts of oil based paint for smooth writing action and to extend marker life. The valve works automatically with each stroke of the marker!
Non toxic paint formula is safe for humans and the environment.
