MIGHTY MUG "The only mug that doesn't spill"!
It's just awesome!
You put it down, you lift it, it's a Classic Mug ...
You knock it: this mug does not tip over ...
How it works: the patented "" Smart Grip "" system automatically creates an air gap when the Mug is placed on a smooth, flat surface thus preventing accidental spills. This "" airlock "" is naturally released when you lift the Mug vertically, it's just Magic! Watch the video here: https://www.youtube.com/watch?v=xZ4_cnpnRzo "
