Car coasters come in sets of 2 and are a fabulous addition to your car décor. Please choose between the two sizes available, 2.5″ or 2.75″ (some sets have one of each). Measuring your car cup holders is highly recommended before purchasing. The car coasters of made of resin, will bend slightly in the summer months, yet will always return to a hardened state when cool. Please always leave flat in the holder.
