Magic Clearboard is a supercharged clear sheet on a roll that sticks with static to any flat surface. Simply roll it out, tear off a sheet along the perforated line and place it on the wall. Write on Magic Clearboard with any dry erase marker, erase and rewrite as many times as you need. You can take down your Magic Clearboard sheet and put it back up again many times without it losing its static cling. Magic Clearboard is made of a statically charged polypropylene sheet. 65 feet of clearboard are included in every roll in 25 perforated sheets that each measure 31.5 x 23.5 Inches. You can roll out as much Magic Clearboard as you want to create an entire clear dry erase wall, or tear off an individual sheet that can be used over and over again.
