innoXstatic-Whiteboards are the portable alternative to traditional and expensive ridge, glue backed whiteboards, flip-charts or cork boards. Any surface, including your desk, can convert into an erasable poster that clings to any dry and clean surface. Unlike traditional whiteboards, “innoXstatic Dry Erase (poly-paper) sheets” provide added electrostatic charge, to stay in place for extended times and are dry erasable on both sides. Easy to transport, just roll it up & place it back into the tube.
