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.

  • Dimensions:
    • 11-ounce: 3.2” D x 3.8” H
    • 15-ounce: 3.4” D x 4.5” H
  • Strong, ceramic construction
  • 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
