Magnetic finger ring(steel ball carrier)

These work pretty good....I live in USA, and have average size hands, and this was huge on me...e GB on middle finger it spins...will have to wrap some cord round to get better fit. But works great!

I bought one of these thinking that it would "monsterously" big for my medium-sized western hand. Nope! It fits perfectly. If it's too small for your ring finger, try it on your pinkie. After all, the magnet goes on the inside. If it's too big ... try your index finger.
I've got my second one on order now.

Waste of money if can't choose size. I wear a size 12 ring, probably bone will fit, I am sure sizes run very small. Note FEMALE hand in photo, if Asian, probably small even for Western female hand, much less a male western hand.
