This clasp is made from zinc, free of lead, nickel, and cadmium. Hypoallergenic. The 2 round spheres house large, strong magnets. This clasp works well with beaded braids. Because of the strength and ease of opening, they work well for bracelets.
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/
