Our Silver (white bronze) Plated clasp or Carabiner (80 mm x 40 mm) allows you to link up our larger link chains into all manner of extensions and closures for longer and varied pieces of your creation. Connect chokers and bracelets into necklaces, make necklaces longer and even turn some necklaces into belts. It links with our larger chain link jewelry. Makes a marvelous key chain too! It's plated in our signature Silver (white bronze) then e-coated clear for durability and shine. Our jewelry is crafted for longevity, and with proper care, you can preserve its beauty for years to come. Just wipe it with a soft-cloth dampened with water, and make sure to dry it completely. Avoid using harsh chemicals or abrasive materials. We recommend putting on your jewelry AFTER using hairspray, lotions or perfumes, etc.
