Summon some spirits (ethereal or alcoholic!) with these four antique Spirit Board Coasters. Perfect for that year-round Halloween fan! 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. SiPlease Note: My coasters are made-to-order just for you.
