Harry Potter Coffee Mug
Harry Potter Hogwarts Castle Heat Reveal Ceramic Coffee Mug - Image Activates with Heat - 11 oz
This Harry Potter Coffee Mug was purchased as a gift to which the person has not received.
Once I got it I tried out the effectiveness of how it changes and it worked better than I expected.
Most coffee cups you can still see the design while in the “cold or blackened” state but this one is completely masked.Promised Review By Renee
