Let your friends, family, and co-workers know how important your morning coffee is with this humorous retro design.
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.
