These innovative 3 ply cutting mats are made of a resilient, self-healing vinyl material that is very durable. As a knife blade cuts into the mat, the surface self-heals instantly, leaving the mat surface smooth and unmarred. They are available in black, green and translucent white. The translucent white mat is ideal for use on a light box. All three colors have a 1" grid pattern and ¼" gradations on the base and left hand vertical edge to aid in cutting. The top surface is non-glare and the bottom of the mats are non-slip.
