This pack of 2 silver and gold Securit Liquid Chalk Markers are smudge and fade proof when completely dry on the written surface. These interior wet wipe marker pens are able to be cleaned easily off any non-porous surface with the use of a damp cloth or sponge. The small 1mm nib makes for a more precise message on the chosen surface whether it be on a smaller chalkboard on a tabletop or on a glass counter display.
