The Marauder’s Map is made to reveal its secrets, so a heat-changing mug feels mischievously appropriate. Add a hot drink and the artwork shifts around the phrases “I solemnly swear that I am up to no good” and “Mischief Managed”.

Mischief reveals itself

Hidden routes and discovery are part of the Map’s appeal. Here, the changing artwork lets that reveal happen in the hand, turning the first hot drink into part of the joke.

Let the hot drink do the work

The 400ml stoneware mug changes with heat. It is not dishwasher or microwave safe, so those care limits should be kept in mind between uses.

A gift for a fellow mischief-maker

Presented in a branded box, it makes a premium Harry Potter gift whose Marauder’s Map reference lands immediately with the familiar “Mischief Managed” wording.
