Custom Heat Changing Mug
- We print your design onto a special layer that reacts when hot liquid is poured in. Once activated, it slowly disappears revealing your design.
- You choose from either a blue or black base tone. Your design is slightly visible under both colours, but less so with the black base.
- The heat activation only occurs on the body of the mug, so your handles will remain either blue or black, depending on the selected base colour.
