Wiping a whiteboard clean requires a soft cloth, paper or, best of all, a piece of felt that won’t scratch or damage the smooth surface in any other way. The most practical solution is our plastic dry eraser device, which has a piece of magnetic foil, attached to its flat underside. This foil serves as the spot to attach a self-adhesive strip of felt. The underlying magnetic foil also provides the means by which the wiper can be easily attached to the writing surface thereby making it conveniently accessible. If after many uses the felt strip can no longer perform its artistic duties, it can simply and easily be replaced with a new one.
