3mm 22ga (.64mm) Click & Lock 14K Gold Filled Jumprings - Pack of 10

Click & Lock Jumprings are easy to use jumprings that lock securely into place with a simple twist of the wrist.  Here is how they work - 1)  Use two smooth nylon jaw chainnose pliers and grip the sides of the jumplock at the 3 o'clock and 9 o'clock positions, with the opening at the top.  2)  Holding the left side steady twist the right side of the ring a quarter turn away from you.  3)  Place your chain, charm or finding onto the jumplock  4)  While continuing to hold the left side steady twist the right side of the ring back towards you a quarter turn past the closed position.  5)  Begin to bring your jumplock into the closed position.  As you twist very gently push the right side in just enough to make sure that the edges of the two ends make contact with each other.  As you reach the closed position you will hear a click!  6)  Twist the right side back & forth very slightly to align the two ends and finish hardening the metal into the closed position.
