Marauder's Map Heat Reactive Footprint Mug
Take a sip out of this magical heat changing mug which transforms with its heat-activated footprints circling from the words "Warner Bros. Studio Tour London – The Making of Harry Potter" on one side, to the Marauder's Map on the other. The magical footprints appear when a hot beverage is added to the mug.
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. This Marauder's Map heat change mug is not microwave or dishwasher safe.
