Color Changing Mischeif Magic Mug

Thanks to its heat-sensitive coating, which reacts to the heating of the ware, the mug changes its color from black to lighter color in an amazing way. When the mug is cold, its color is black, and the image is hardly noticeable. But when filling it with hot drinks - tea, coffee, milk or water, its color becomes lighter and the printed image gradually appears.
