Sip in skeptical style with this tongue-in-cheek “Mars Is Flat” coaster—perfect for flat-map lovers, sarcastic science fans, or anyone who enjoys a little planetary humor with their drink. It's heat-resistant, spill-proof, and absolutely not peer-reviewed. 3.75x3.75 in. coasters are made from masonite hardboard tempered material featuring a cork bottom. Wipe clean with a damp cloth, not dishwasher safe.
Bold design. Durable build. Light-years of laughs.
Because every planet needs its own conspiracy theory.
