The Duo is an innovative ergonomic handle that attaches very easily to everyday mugs, cups, glasses and bottles, to give the user an additional easy to grip handle, and making the cup or mug far easier to handle, reducing the risk of embarrassing spills.The Duo is a great alternative to 2 handled mugs or beakers, allowing everyone to use the same mugs as family and friends, and is also ideal for using when out and about in cafes and restaurants. DUO\'s wraparound style will protect hands and fingers from hot mug surfaces, whilst its unique clip on design makes it easy to attach and detach without fuss.
