Marvel Heat Changing Mug - Hulk
This Marvel heat changing mug is sure to give a super start to your morning. Cold, the mug shows the Incredible Hulk and his logo and a hole in a brick wall. When hot liquid is poured in, the mug transforms to reveal pieces of broken wall and Hulk's fist smashing through the hole. Once the drink is finished the mug returns to its original state as it cools.
