The Mug that won't fall over! - You need to try it to believe it.
Mighty Mug is the world's only travel mug powered by an innovative and patented Smartgrip Technology. Simply place Mighty Mug down on your desk and it creates a powerful airlock which allows Mighty Mug to resist accidental knocks to help avoid spills. When you lift Mighty Mug the pressure is instantly normalized allowing the airlock to release and Mighty Mug to lift naturally.
