This Disney Frozen tapered heat changing mug is sure to get your morning off to a warm start! Cold, the mug shows character art of Olaf against a navy blue background with a swirl of snowflakes behind him, including his quote, Some people are worth melting for on the reverse. When hot liquid is poured in, the deep blue background transforms to a light blue, revealing background line art of Anna and Elsa on the side, while the back of the mug shows another of Olaf's famous quotes, I like warm hugs. Once the drink is finished the mug returns to its original state as it cools. Packaged in a printed gift box, it makes a lovely gift for any Disney fan.
