Harry Potter - Marauder's Map Heat Changing Mug (DELIVERY TO EU ONLY)

Take a sip out of this magical Marauder's Map Heat Changing Mug, which transforms from a black ceramic to reveal the Marauder's Map once hot liquid is poured in. The Marauder's Map is a magical map that uncovers Hogwarts School of Witchcraft and Wizardry showing every classroom, every hallway, including all the secret passages that are hidden as well as the location of every person in the Hogwarts grounds.

Once you've finished your delicious drink, simply utter the words 'Mischief Managed', the secret incantation to make the map become invisible. This mug is not microwave or dishwasher safe.
