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