Our Colour changing Cambridge Wow Mugs are a ceramic promotional mug with bright, vibrant printing and a stunning visual effect! Created by applying a coloured, heat sensitive coating to the outside of a Cambridge ceramic mug, which is then personalised using the dye-sublimation print process.

When hot liquid is added, the heat sensitive coating becomes transparent revealing the printed image beneath, strong and bright. As the mug cools, the heat sensitive coating is restored to its original colour. Hand wash only! The Cambridge WoW Mug may also be screen over-printed with a permanently visible message to convey the brand or advertising message when the mug is cold.
