winter warming by Benjamyn333 from uk

The graphic snowman printed on the mug has been designed as a Christmas gift to promote awareness on climate change at a time of the year when energy wastage is most common. The use of thermo-graphic inks allows the graphic of the snowman to change and melt when hot water is poured into the cup, serving as a reminder to its user the potential consequences of wasting energy.

The graphic will also work on stickers that can be placed on other objects that may be a cause of excess energy usage, for example, kettles, radiators, etc.
