With a textured, copper surface accented by small, inset crystals, this clasp makes a glamorous statement. The magnetic closure is easy to operate, while the generous loops will accommodate 1.0mm leather or multiple strands of thread. The Nickel Free and Lead Safe plating is naturally hypo-allergenic (Meets California Prop 65 Requirements). We do not recommend magnetic jewelry for anyone who is fitted with a Pacemaker. It is also not intended for jewelry worn by young children. The end rings are soldered so we recommend 5mm/18gauge jump rings in matching finish, if needed.
