You're sure to create a stylish look with the help of the Gold-Plated Etched Barrel Glue-In Magnetic Clasp. Each barrel features a small open hole in the center. Slide the end of a necklace or bracelet strand through the hole and crimp the barrel clasp to the strand, close to the opening in the barrel. Test the crimp with the magnet in place to ensure the magnet will lay flat in the barrel and trim the crimp or string accordingly. These barrel clasps feature an etched surface full of dimension that will enhance your style in all new ways. They display an elegant golden glow, perfect for classic looks. Please note that magnetic clasps should not be worn with pacemakers.
