This Harry Potter Marauder’s Map cold changing glass is sure to get your morning off to a mischievous start!
At room temperature, the front of the glass shows a Marauder’s Map design while the back features the words “I solemnly swear I am up to no good” which is the password used by Harry Potter to open the iconic map from the film franchise.
When cold liquid is poured in, the glass transforms to reveal a wraparound map design. Once the drink is finished the glass returns to its original state as it warms back up to room temperature.
An essential for any Harry Potter display and a great addition to any Marauder’s Map collection.
