Description About the Tintin colour changing magic coffee mug Because of its heat-sensitive coating, which reacts to the heat, the mug changes its color from black to white When the mug is cold, it 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. The mug is a delightful, original and impressive gift for your family or colleagues. Artwork is slightly visible when cold There is a 20mm section on either side of the handle that does not get printed
