A new 'locking' jump ring, that won't come open accidentally. The perfect compromise between the versatility of open jump rings and the security of closed jump rings. You will receive the rings in the open position. Assemble your piece, then follow the directions provided below to lock the jump ring in the closed position. 1. Use two smooth or nylon jaw chain nose pliers to grip the sides of the Jump lock at the 3 o'clock and 9 o'clock positions, with the opening at the top. 2. Holding the left side stead, twist the right side of the ring a quarter-turn away from you. Place your chain, charm, or finding onto the Jump lock. 3. While continuing to hold the left side stead, twist the right side back toward you a quarter-turn past the closed position. 4. Begin to bring your Jump lock into the closed position. As you twist back, 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. 5. Twist the right side back and forth very slightly to align the two ends and finish hardening the metal into the closed position. Once the Jump lock is clicked into place, your jewelry is secure against regular wear and tear. †Unlike regular jump rings, these rings will not open accidentally. Please be patient when working with this new product, once you get the hang of it, you will wonder how you ever lived without them. PLEASE NOTE: †Make sure you are happy with your design before locking your rings closed. †These locking rings are one-use-only. †They can be opened again with your pliers, however, it is not recommended. If you close the ring again, the locking ridges will be worn down, and the ring may lose its 'locking' capability. Measurements: 6mm outside diameter. Wire is 18 gauge, or .040 Inch.
