Our natural stone coasters are made from chiseled, black slate for a rugged look. Made from a mixture of clay minerals and other small minerals such as quartz and calcite, slate is durable, strong and won’t stain. This particular slate coaster features a vinyl design of a K9 German Shepherd positioned in the center of a 6-pointed sheriff star. Each coaster features a cork backing to protect furniture from scratches and prevent the coaster from sliding on slippery surfaces. Choose from a single, double or quadruple pack of coasters as a gift for a proud sheriff or deputy who handles a K9 unit. They make great gifts for retirement, promotion, holidays, housewarming or birthdays. Shop now and show your support and pride for law enforcement with this unique coaster.
