Pack of 50 pieces. BLACK OXIDE Plate or Gunmetal color. These wire guardians are a perfect fit combined with the black crimps and gunmetal Ball and Socket clasps listed for sale in my store. Wire guardians protect your wire or other stringing materials from undue wear, particularly where it loops through a clasp. Use them the same way as French wire or bullion. Wire guardians are also a fantastic alternative to closed jump rings or split rings used at the ends of your jewelry creation
