Our take on the Not Flat We Checked Funny Flat Earth Coffee Mug

A ceramic coffee mug printed with the joke "Not Flat We Checked" aimed at flat-earth believers. It is dishwasher-safe and microwave-safe, so it works as an everyday mug rather than a display piece. The humor is the whole point; the mug itself is a standard ceramic cup with no special insulation or lid. It suits people who like science jokes and gag gifts, and it competes with other novelty mugs on the strength of the print, not on build.
