Solemnly swear I am up to no good Mug

Custom designed mug with your favorite Harry Potter saying, “Solemnly swear I am up to no good” is on one side has this say, and going to the other side are little foot prints going around the mug to the other side, the other side shows a map, with the same saying on the map, and under the map it says Mischief Managed. Starting with a dark charcoal colored mug, when any hot beverage is added into the mug, your image is fully revealed. This is 1 mug, that I have slowly turned around and taken pictures of.

I fully design the mug, so if there is any other design that you would like to be done in this magic revealing mug, let me know and I will be happy to help. :)

This is a Printed Graphic that I heat press directly into the ceramic mug with a special coating, using a commercial grade mug press.
