Add some signature Trolls sparkle to your morning routine with this fabulous heat changing ceramic mug featuring artwork of the iconic 90s toy with a black hair-do on the front against a yellow background, while the reverse shows the words, Me before coffee in black text. Simply pour in hot liquid to magically transform the Troll\'s hair and the word coffee to a fantastic rainbow colour! The mug returns to it\'s original colour as it cools. Packaged in a printed box, this is a wonderfully nostalgic gift for anyone who adored the Trolls when they were young.
