Harry Potter Marauders map magic mug

About our Harry Potter Marauders map magic mug

Because of its heat-sensitive coating, which reacts to the heat, the mug changes its color from black to white . When the mug is cold, it is black, and the image is hardly noticeable. But when filling it with hot drinks – tea, coffee, milk or water, its color becomes lighter and the printed image gradually appears.

The mug is a delightful, original and impressive gift for your family or colleagues.
