This heat changing mug is sure to brighten up your morning brew. Cold, it features an exclusive Jolly Awesome design of a cheeky dog with his own morning coffee and the words 'Might Be Coffee' on the back. When hot liquid is poured in, the mug changes to a lighter blue colour and the words 'Might Be Vodka' appear underneath the original text. Once the drink is finished the mug returns to its original state as it cools. A perfect gift for those who love caffeine, and something a little stronger.
