Flying Rainbow Witches Magic DISAPPEARING IMAGE 15oz Coffee Mug
Featuring the Bare Witches Design byh R66Labs
It looks like a plain black or blue mug, but add some coffee and – magic – the 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.
