Material: Pewter plated with 99.9% silver. Free of lead, nickel, cadmium. Hypoallergenic. There are other clasps that look the same but are lessor quality and do not have secure magnets. You get what you pay for.
This is a very popular clasp. Customers love the slim profile and ease of use. The curve of the clasp follows the curve of the wrist and creates a more secure closure. It has a very strong magnet and a brilliant finish. When closed, the protruding tab is flush with the top surface of 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/
