This Batman heat changing mug is sure to cast a light over your morning brew. Cold, the mug shows Batman looking out over the city. When hot liquid is poured in, the mug transforms to reveal the Bat-Signal in the sky and the words 'Gotham City Needs Me'. Once the drink is finished the mug returns to its original state as it cools. An essential for any Batman fan.
