This mug looks like a normal mug when its cold. But when you put your morning coffee in it? It will reveal the design and say:
• Black glossy finish when cold
• Reveals the print when exposed to hot liquids
• Dimensions: height - 3.54'' (8.9 cm), diameter - 3.35" (8.5 cm)
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.
