Harry Potter Marauder’s Map Heat Reveal Change 20oz Ceramic Mug
This black Harry Potter Marauder’s Map mug is a large 20oz mug. Officially-licensed Warner Brother’s Harry Potter merchandise. It has the saying “I Solemnly swear that I am up to no good” on one side and a map of Hogwarts on the other. It larger size will blow other mugs away. Footsteps appear on mug
Large size is great This mug is gigantic so I can fit a ton of hot tea in it. The heat map reveal thing doesn’t stay active for all that long, but I don’t really care about that too much. I like the general design and size of it enough to offset that one minor gripe.
