Mozi is like a slinky for your arm. It spins continuously and effortlessly as it moves up and down – from one arm to another, or as you pass it to a friend. Watching it glide is just as mesmerizing and addicting as it is to use. Get your groove on and feel the movement! From ring to ZING! Mozi transforms into mystical entertainment when taken out for a ride. To activate mozi, place your hand through the ring, raise your arm, and let mozi roll. For a smooth ride, mozi moves best on bare skin. mozi lays flat when stored.
