This clasp is made from zinc and is lead and nickel free. Usually only cord ends need to be inserted into clasp, not beads. This clasp works well with multiple beaded braids or flat fiber braids. The security prongs require a slight twist to open the clasp.
The only glue I recommend for attaching clasps to beaded and fiber braids is 2 part epoxy glue as it is the only glue to forms a secure, permanent bond. Step-by-Step instructions for using 2-Part Epoxy are on my blog http://kumihimoresource.com/kumihimo/2-part-epoxy/
