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.

Three-pack arrived decently protected in individual containers, and magnets worked great! One minor quibble about the packaging- I would've preferred if the ring boxes didn't have metal parts for the magnets to stick to; instead of hinges, screw tops would've been nice. That way each ring could sit in the space between the cushions and not get in the way of opening the box. I'm not sure if that interference made a difference or the hinges were going to break anyway, but it would've been nice if these sturdy boxes were reusable instead of more plastic waste to ship the goods with...it's OK if they're supposed to be disposable but, with all the material used, they could've been nice longterm storage for keeping the rings separate. Just a thought.
