Post-it® Easy Erase Whiteboard films are stain-proof dry erase surfaces that quickly transform smooth surfaces into reusable whiteboard spaces. Simply unroll, peel and stick to create a writable area on walls, desks, cabinets, glass, painted steel, existing whiteboards or chalkboards. The roll format can be trimmed to size, making it ideal for refreshing old whiteboards, covering larger wall areas or creating custom planning and collaboration spaces at home, school, in the office or classroom.
