This magnetic clasp is zinc plated with copper, and is free of lead, nickel, and cadmium. Hypoallergenic. Hole is large enough to accommodate 2-Drop Kongoh beaded braids using up to size 6º seed beads or 8mm round leather. This clasp is super strong, perfect for bracelets or necklaces.
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/
