Who doesn't love a good surprise? With this color changing coffee mug, you're definitely in for a great one. This mug has a black matte finish when it's empty. But when it comes into contact with a hot beverage.
Note: You shouldn't put the mugs in a microwave or dishwasher since it can damage the coating.
The mug reveals my signature message to remind you of your greatness when having your HOT drink of choice.
