Each ZipWall^® Mat Starter Kit features a durable, reusable, non-skid base and includes a pad of 30 adhesive sheets. The base is 25″×37″ and the mat 24″×36″. Slip-resistant backing holds the base firmly in place on carpeted floors and on smooth floors like vinyl, concrete, and tile. The base is portable and does not damage the floor surface. Adhesive sheets are individually tabbed and numbered so you always know how many are left. When the top sheet gets dirty, simply peel it off to expose a clean one.
