Tiny lobster claws work perfectly to attach a charm to the zipper head. These tiny lobster claws are perfect to attach to a zipper.

It is quite secure, but not infallible. It also holds very securely. Strong magnet, so very secure.

Beautiful and dainty. Absolutely secure and worth money. They are truely wonderful.

This product is a life saver. It truly alleviates having to struggle to put on and take off. But if you don't watch a toddler, chances are you'll be just fine.

The magnetic clasp is exactly what i needed. It replaces having to open a tiny clasp on a delicate choker without adding length. Converting the clasp to a magnet was a reasonable solution.

These are flimsy clasps and a waste of money. They are so flimsy i can't invesion what they would be good for. Very cheaply made.

Clasp is too small and doesn't fit on my necklace. Aren’t they suppose to be “extenders’ for necklaces? Better quality is worthless if the magnet is so small.
