Unlike traditional 4' x 6' black mats, PuzzleTiles are easier to handle or relocate, have less odor; and are more colorful. Made from dense recycled rubber; these 24" x 24" tiles are 3/8" thick and feature interlocking tabs and slots. Tiles are easy to cut or trim with a standard utility knife and require no adhesive - "puzzle" edges simply lock together! Available in black, speckled grey, and speckled blue. Custom colors also available. For more information call us at 1-866-656-8023
