This Harry Potter cold changing glass is sure to get your morning off to a magical start.
The black glass features a repeat print of the Deathly Hallows symbol and a large version in grey on the front.
When cold liquid is poured in, the large Deathly Hallows symbol transforms and turns green.
Once the drink is finished the glass returns to its original state as it warms back up to room temperature.
Housed in a printed gift box, this is an essential for any Harry Potter fan.
