Take a trip to the wizarding world of Harry Potter with this marvellous mug.

Officially licensed and perfect for the potty about Potter in your life, this mug may be in our muggle world but it’s still pretty magical.

At first glance, you see ‘I solemnly swear I am up to no good’ printed on a black background with a few little footprints around the back. It looks like a pretty standard mug but if you say the words printed on the mug, the magic kicks in. Just make sure you also add hot water at the same time.

The once black mug begins to change into right before your eyes, revealing a special message stating that ‘Messrs Moony, Wormtail, Padfoot and Prongs are proud to present (slowly rotates mug whilst humming Harry Potter theme) Marauder’s Map!

A perfect gift for fans of the books or movies, the Harry Potter Heat Change Mug even has ‘Mischief Managed’ printed on the bottom of the mug, to make sure you keep this map a secret.
