Saturn's Rings Only
Nerds know best: Water rings aren't fun, and the best way to prevent them is with a set of solar system-inspired coasters. Made from a sturdy, easy-to-clean hardboard wood with a cork back, this set will prevent you from falling down the black hole of coffee table scrubbing once and for all. It also makes an A+ gift for astronomy geeks, science teachers, or anyone who appreciates the wonderment of the great beyond (or the wonderment of furniture upkeep). Made by Sam and Steve in Albuquerque, New Mexico.
