Use as a semi-permanent whiteboard surface and can be applied directly to most flat surfaces. Roll up and re-use up to 25 times. Much thicker than film or foil therefore minimal creasing. The kit contains a pen clip, a cloth clip, a Show-me Drywipe Marker and a cleaning cloth. The board is designed to be slightly less than 1200 x 900mm to allow for the standard frame of wall-mounted boards of this size if you want to refresh an existing whiteboard surface. Actual size 1140 x 840mm.
