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.

My son in law has wanted this for a couple of years and was surprised so excited to get it!! It works exactly as advertised. He uses it almost every morning for his coffee.

Mischief Managed

We bought this as gift for a family member and she absolutely loved it. She even made tea right away to see the heat change difference! It's a perfect gift for a big HP fan!
