Color Changing Mug – First Coffee, Then I’ll Walk The Dog

Description

This is a COLOR CHANGING MUG, which starts out ALL BLACK. Thanks to special thermal coating, what appears to be an ordinary black ceramic mug, slowly begins to reveal “First coffee, then I’ll walk the dog”.

Hand washing recommended. Not microwave-safe. Do not place them directly from cold water immediately into boiling water, or the mug may crack.
