Clowns! Is there anything more unsettling? These four creepy clowns are sure to get the conversation going (or the nightmare started) at any Halloween gathering. Each coaster set comes in a decorative wrapper which make them an easy choice for that affordable ready-to-go gift! With an MDF base and a cork back every coaster is sealed with a waterproof, heat resistant resin (similar to that used to coat restaurant bars or tables) that provides a glossy finish and guarantees a long life.
