The HotCold Mug changes colors when hot

by yogesh

One of Charles and Marie’s claim to fame is the OnOff mug that they launched, but carrying on the tradition is the HotCold mug. Unlike the OnOff that indicated whether there was any drink in the mug, the HotCold tells you if your choice of beverage is very hot or not. White on black when the drink is COLD and Black on white when the drink is HOT!

The HotCold Mug is on presale here for $25.
