This little magic fella appears black but then teaches you the anatomy of a hop when you pour coffee into it... like most people.
• Black glossy finish when cold
• Reveals the print when exposed to hot liquids
Note that in some instances the coating might not be 100% opaque and an outline of the design might peek through a little. You shouldn't put mugs in a microwave or dishwasher since it can damage the coating.
