Thermo Mug - Green,Silver

Mighty Mug was developed by a team of mechanical engineers and industrial designers who spent 3 years perfecting Mighty Mug and it's patented Smartgrip technology. Not to be confused with a magnet or suction, Mighty Mug’s Smartgrip at the bottom of the cup creates a vacuum that airlocks the mug onto the cup’s surface - effectively preventing it from being knocked over. The vacuum is released instantly when the mug is lifted straight up requiring no extra effort.
