Disney's Nightmare Before Christmas Morphing Mug

Up for purchase is a brand new/ NWOT Disney's Nightmare Before Christmas mug. The mug is black with a color changing image of Jack Skellington surrounded by snowflakes from The Nightmare Before Christmas on the front. The image appears when hot liquids are added to the cup. The back of the mug has the words "Nightmare Before Christmas". The cup is brand new and has never been used, however it does not have any tags on it, as it was a wholesale item.
