These magnetic clasp’s are very sturdy and strong, and an excellent value for the money. Sturdy enough for natural stone necklaces. The magnets are not quite as strong as i'd like, but overall they are fairly secure.

This is a clever gadget that is designed well for putting on a bracelet or watch. Makes it easy to put a bracelet on. A helpful tool for delicate bracelets that are difficult to clasp.

There were supposed to be two items in the box. Didn’t receive it.
