Round 330ml stoneware coffee mug which has a unique thermochromic coating. This allows the branding to appear ‘magically’ when hot liquid is added and then disappear again as it cools. Chameleon is manufactured for spot colour or full colour wrap-around branding. The thermochromic coating can be overprinted but this print cannot be registered with the branding underneath. It is presented in a black gift box and handwashing is recommended.
