Set of 4 coasters, as shown in photo. Awesome addition to your Man Cave or Geek Cave. Be the first kid on your block to get your hands on these brand new unique creations from AllyBoo's. These coasters measure 5 inches tall by 3.5 inches wide. These are solid and made from 1/4 inch aspen wood with felt tabs on the back to protect your tabletop. The comic covers are decoupaged onto the wood and then three layers of semi-gloss polyurethane are applied for maximum durability and protection.
