Pour in hot coffee and watch the black pixel heart on this color changing heart mug fill up with red from the bottom, a bit like a video game health bar. As the drink cools, the heart empties and goes back to black, ready for the next round. In a white 330 ml ceramic body, it makes a playful Valentine's or anniversary gift for a partner or a gamer who already owns plenty of mugs. It is part of our Kitchen Essentials collection.

Frequently asked questions
How does the color changing heart mug work?
A heat-sensitive print covers the heart on this color changing heart mug. Hot liquid warms the ceramic, so red shows through, and cooling turns the heart black again.
Can I put this heart mug in the microwave or dishwasher?
No. Hand wash this color changing heart mug with a soft sponge, and keep it out of the microwave and dishwasher, as heat and scrubbing can spoil the design.
Why is my heart mug only half red?
The change follows the heat of the drink, so a half-full or lukewarm cup shows a partly filled heart. Fill the color changing mug higher with a hot drink for a full red heart.
Is the outside of the mug hot?
Yes. The ceramic gets hot when it is full, especially during the color change, so hold it by the handle. Keep hot drinks away from young children.
