It’s magic I tell ya! Start your day off with some real magic in this cool Harry Potter Hogwarts heat changing mug. Featuring the school that’ll make a wizard out of you, even your tea can be magical. This standard sized mug features a decal that changes with the heat. When cold the mug is black, with just the Hogwarts crest and some candlelit windows visible. However, once a hot cuppa has been made, the moonlit buildings of this famous school appear from the darkness.
