Black Color-Changing Hidden-Message Mug – 11 oz

Watch the surprise appear with every hot drink! This 11 oz color-changing ceramic mug has a black exterior when cool. Once a hot beverage is added, the surface transforms and reveals a cleverly disguised hidden-message design.

Turn the revealed design sideways to uncover the bold adult-humor message: “FUCK THIS SHIT.” When the mug cools, the exterior gradually returns to black—making every cup a fun conversation starter.
