Our car coasters come in sets of two and are printed to order in house using high quality materials and processes. The print is permanent and will not fade, crack or peel. There may be slight differences in each print since they are hand made. The car coasters are made of neoprene material. They have a soft polyester front with a black rubber backing. They measure 2.56 in diameter and are .22 thick. Print is on front side only.
