This Harry Potter heat changing mug is sure to cast a magic spell over your morning brew. Cold, the mug shows the famous Hogwarts Crest featuring all four houses on a black background on the front, and the words ‘Hogwarts School of Witchcraft and Wizardry’ on the back. When hot liquid is poured in, the mug transforms to reveal Hogwarts School against a night sky, with several dorm room windows lit up from the inside. Once the drink is finished, the mug returns to its original state as it cools. A truly magical gift for any Harry Potter fan.
