Gorgeous portrait by famous dog artist M.K. Zeppa - Dye sublimated directly into rubber backed polyester material. The poly is absorbent enough to make great coasters and the rubber helps to resist slipping. Coasters measure 4 by 4 inches and come packaged 4 to a clear reseal-able bag. To clean, simply wipe with a damp sponge. Available for over 150 breeds!
