3 grand kids loved them,

Got three -- different colors so my 3 grandkids wouldn't fight over which was whose. They were entranced. Easy to use, even for the 3 year old who was just having his birthday.More > < Less


Worth it!

Don't buy the cheap knockoff you see locally. This is great quality. Mine has stood up to nonstop high school students- Not destructive kids exactly but not easy on a toy, and, this is as great as when I first took it out of the package.More > < Less


I brought it to work!

I brought this to work on a Saturday where the atmosphere is a little more relaxed than during the rest of the week. I had coworkers stick out their arm and lift up--always a big smile and "Wow, what IS this?" I shared with customers the same way while they were waiting during transactions, I gave out this website info multiple times. There were so many smiles and pure joy spread thanks to this toy! The next week, a coworker came with her own and the fun began again as we all reached for it anytime we had a spare moment. There are knock-offs in plastic as well as metal that we've tested, but Mozi always wins!More > < Less

We gave this to our 5 year old grandson for his birthday. Both he and his 6 1/2 year old brother caught on right away and loved playing with it! Their Mom and I enjoyed it too!More > < Less

This is both mesmerizing and calming all at once. This is a house favorite. I also have a friend that is a counselor who uses it in her practice.

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.
