Overview

The world of Harry Potter comes alive with this "I Solemnly Swear...Mischief Managed™" heat changing mug. Fill this mug with hot liquid and the text changes from "I Solemnly Swear That I am up to No Good™" to "Mischief Managed™." This 11-ounce mug changes from black to a creamy, off white color, completing the transformation. This mug makes a great gift for any Harry Potter fan. In our new, improved version of this fan-favorite gift, the disappearing action is much more complete, although you'll still see a hint of the first part of the spell after the hot water is added. Also, while you should still wash the mug with care, the artwork is much more resistant to scratching. This mug is not microwave safe and is not dishwasher safe. Hand wash only with nonabrasive cleaner and soft sponge.

Works well, a bit boring

The mug itself is nice. I just wish it had a better design, like footprints or something. It's just a bit boring. Yes, I knew that when I got it. Just giving my honest thoughts.

Love it!

I have been waiting for someone to buy this for me for a long time! I finally broke down and bought it myself and I'm not disappointed!
