GBSTORE 3 Pcs Different Size Strong Magnetic Ring PK Magic Tricks Pro Magic Props

Not to buy very bad quality

These have a strong magnetic force. I'm not sure if they're "rare earth" magnets but they are quite strong. I was able to use one on my finger to perform a magic trick with a card, where I pass my hand about an inch over the card and it lifts into the palm of my hand. It wouldn't work unless the ring was very strong, since the card has only a small, dime-sized normal magnet on it. But the trick works! However, one of my kids has dropped a ring on tile, and it shattered! Also, I dropped one on concrete and it instantly shattered. So they are very fragile. In all fairness, they warn you about this in the description.

Same size

Actually my use case is to simplify keep magnetic stir bars in the test tubes when dumping/cleaning out contents. This ring is now one of my water testing supplies as wearing allows quick and fully overturned test tub actions without the need for fishing out or losing these little pill shaped buggers. I found the ring sizes practical/useful for standard male sized hands. Mine are slightly smaller than average and that found between two of the three sizes allow pointer, middle, ring finger options to fit perfectly snug but easy to remove. As to magnetic strength - these little jewels are highly attractive - Hey and they look pretty cool too! I also appreciate the included casings for storage. Altogether a well built and packaged product.

Seems magicians and such gravitate to these for classic magic tricks. I'm not one of you. I use these to trigger reed switches in random electrical things I make. There's nothing like the sense of wonder when you "trick" the younglings around you when you grab that minecraft torch you made them but for some reason whenever you grab it it lights up a different color! These rings do seem to be on the fragile side, but we haven't broken any yet. We've been rather gentle with them from the start. They seem to be made of the typical ceramic magnet material, merely formed into a ring and given a thick and shiny paint job. Quite rigid, but I'm sure would break in half if dropped onto a hard surface or rough housed with too much. If you've ever had a hematite ring, it's like that.
