The Rotating Cutting Mat is a cutting mat that consists of two independent pieces.
The top piece is the actual cutting mat with a measuring grid, and the bottom piece is light grey/white with 5 non-slip disks on the back. The top piece has a little hole in the middle of the back side that fits the metal pin in the center of the top side of the bottom piece. The pin works like an axle or spindle that allows the top to move freely. This makes the mat spin around.
