Harry Potter - Heat Changing Mug
- This wonderful Harry Potter Hogwarts Heat Changing Mug captures the wonder of Hogwarts School, allowing you to enjoy a magical tea-break. This standard sized mug features a decal that changes with the heat. When cold the mug is black, with just the Hogwarts crest and some candlelit windows visible. However, once a hot cuppa has been made, the moonlit buildings of this famous school appear from the darkness. The perfect gift for any Harry Potter fan, the Hogwarts Heat Change Mug offers you a great mug from which to enjoy your next mid-film cuppa. Pour in your favourite hot beverage and watch as Hogwarts appears from the darkness.
