Principal Nutrition Facts Mug

Buyers have the option to personalize the mugs by adding a name, a personal message or a photo on the opposite side of the mug.

Buyers also have the option to select a regular white mug, a color changing mug, or a white mug with an interior color. The color changing mug starts off the color of the mug and turns white, revealing the design when hot liquid is poured inside. Mugs such as the red or teal color changing mug will show the design prior to being heated. The black mug is not 100% opaque, meaning you may see the outline of the design prior to heating it up.
These mugs is microwave safe!
A ding or scratch to the mug can mess up the outside design, causing the initial black coating you see at room temperature to mess up. so, although it is dishwasher safe, we'd recommend hand washing to prevent situations like that.
