Who doesn't love a good surprise? With this color changing coffee mug, you're definitely in for a great one. This O-JOE mug has a black matte finish when it's empty. But when it comes into contact with a hot beverage, the mug reveals a beautiful print that'll always make you smile when having your drink of choice.
• Black matte 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. Also, you shouldn't put the mugs in a microwave or dishwasher since it can damage the coating.
