This type of clasp is commonly used for hoop earrings and provides a secure and easy-to-use closure. **

The chain clasp works by inserting the small hook on one end of the chain into the loop on the other end.

It's important to inspect the clasp and bracelet to determine the specific reason why it won't close. **
