Love it


So simple but amazes children and adults!


Whatever it does, it does it well!


I bought this for my grandson. I have no idea what it does or is supposed to do. It is for a grandfather to be confused and a grandson to fully understand it without reading any kind of instructions. Having said that, my 9-year-old grandson loved it and thanked me profusely. I thought it was a Slinky on steroids.More > < Less


Everyone should have one of these!


I ordered two of these for my nieces and will send them soon. They are so much fun to play with! I highly recommend buying them for young relatives but have them sent to yourself so that you can play with them~~they will bring a smile to your face!More > < Less


A hit with granddaughter.


My wife and I sent one of these to our granddaughter just on a whim. It's been a real hit. She plays with it with her parents and with her friends across the street. Highly recommended.More > < Less

About MOZI

Flow Ring

This is a slinky-meets-fidget toy for your arm. It’s one of those simple, yet addictive toys for people of any age.

Mozi slips over your arms and spins in mesmerizing patterns across it. Roll it from arm to arm or friend to friend. Then, once it’s made its rounds, just fold it flat by turning it counterclockwise between your hands.

Its smooth, caterpillar-like movement works best on bare skin. Everyone here at The Grommet got a kick out of playing with Mozi and we’re keeping a few around for fun.
