Darling coasters made with space-themed cotton fabrics. One has a light blue background with aliens in UFO's, airplanes, and helicopters. The alternating fabric is dark blue and decorated with rocket ships and planets. There is a set of 4 coasters. Each is roughly 4 1/2" (11.43 cm) square. The backs are divided with half of each fabric used. There is a layer of batting inside to absorb moisture. Use or give as a nice Man or Woman Cave gift or a gift for your favorite scientist. We don't take returns, but will work with you to make it right. We love our happy customers.
