Neomagnetic Ring by Leo Smetsers (3530)

Imagine a Neo Magnetic ring made
from stainless steel and polished by hand. The Neo Ring is not brittle
like many that are currently on the market and will not smash, crack or
break. The best thing about the Neo Ring is you are in complete control
of activating and deactivating the field. So now you can perform
routines with the knowledge you are not going to get stuck to anything
unexpectedly. Yet when you’re ready, you’ll be like a real life magneto.
