Tintin colour changing magic coffee mug

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
