With the Pentel SMW56 red chalk marker you can make drawings, decorations and texts on non-porous surfaces (paper, glass, chalkboard, plastic, metal and whiteboard). Thanks to the 8mm - 16mm chisel nib, you can write clear texts and markings. With the handy pump system you can easily fill the nib with red ink. This Pentel chalk marker is suitable for indoor and outdoor use. The ink does not run when it gets wet. Remove your design in an instant with a damp cloth. Pentel's SMW56 chalk marker is not suitable for painted wood, MDF and vinyl records.
