A self-contained, instant repositionable whiteboard includes a roll of 13" wide film in a dispenser box with slide cutter. To use, simply pull out the desired length of film, slide the cutter to cut the film, and position on any indoor surface. Professional-grade, ultra-thick, static cling film clings on either side with its embedded static charge to glass, drywall, metal, plastic, wood, brick and marble. It can be used without tape, pins or adhesives so it leaves no residue behind. Write on both sides with dry-erase or permanent markers, and it won't bleed through. When done, roll up your work and take it with you. Ideal for collaboration, planning and instruction. Environmentally friendly film is safe, chemical-free and additive-free. Refill film rolls are sold separately and easily inserted.
