smiley colour changing mug

Sold out

Go from dead to alive and smiling with your morning coffee.

Just fill the mug with your favorite hot drink and watch as the mug changes to a big smile to greet you.

These mugs are heat sensitive and color changing. Mug is black (and very much dead) before the hot beverage is put in the cup and then the mug goes smiling with a bright yellow.

• 300ml ceramic mug with heat-sensitive color-changing ink
