Heat-reveal Mug

300ml white earthenware mug, starts off black and reveals your full colour design when filled with hot water!
(The mug has a specially formulated heat sensitive thermo-chromic coating, so when hot water is poured into the mug it turns back into its natural clear colour, exposing your print underneath and disappearing again as the mug begins to cool after use. Recommended for hand washing only. Please note we cannot match colours particularly accurately on ceramics.)
Print area 220mm wrap x 92mm high.
