These Diamond coasters are a perfect match to go with the Diamondback cutting board. Walnut, maple, and cherry hardwoods are beautifully combined into a diamond pattern centered on the coaster. The coasters are 3 3/4" square and come with a cork backing to protect your table top. Treated with a water resistant coating, these coasters handle moisture quite well. The Diamond coasters come in a set of four and include a walnut base to store them when not in use.
