Style: Color Morphing Mug

It looks like a plain black mug, but add some coffee and – magic – your funny design, cool pattern, or special photo is revealed. This mug turns heads. It is made with a special, heat-sensitive coating, so, when any hot liquid is added, it changes color to reveal your design against a bright, white background. It may seem simple, but, trust us, a morphing mug never fails to surprise and delight.

  • Hand wash recommended; microwave and dishwasher are not recommended due to the special, heat-sensitive coating that gives this mug its magic
  • Meets FDA requirements for food and beverage safety

STFU Morphing Mug

STFU Morphing Mug

A colour-morphing mug that politely reveals your need for quiet time. And even when you've become disgusted with your burnt coffee and found you can't drink all of the nasty bilge, the dregs will keep the half-empty bottom of the mug warm enough to display that all-important STFU. Cranky cleverness!

The black cat in the window mug is magical. I didn’t know what a morphing mug was when I got it. When hot the cat appears and cold it looks like a plain black mug. .

Creator Review
I wanted to create a Christmas gift for family and friends. I used a photo I had taken of my peacock. When the mugs arrived I was anxious to try it out. It’s amazing to watch as the peacock “magically” appears! The mug itself is great quality and the morphing is beautiful to watch! The colors are amazing!
