Who doesn't love a good surprise? Imagine offering a mug to a friend or a someone who is really proud of their HAIR, they pour, their favorite hot beverage in it, sit to chill and happiness is uncovered to them. Do you care about making a long lasting memory for that person. Simply give them this mug and imagine the smile on their face every morning when they sip their coffee or tea thinking about you.
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.
