The new GRAFX™ ART MASKING LIQUID MARKER contains a special masking liquid that can be rubbed off, in a convenient pump marker. Apply the masking liquid on the surface not to be painted, next add colour, let dry briefly and rub off with a finger or a rubber. Due to the patented and refillable marker technology, the art masking-tool is unique for all applications in marker, acrylic and watercolor or for sketching in the design- and graphics sector.
