50x Jumpring in aluminium, 9x1.2mm

To open or close a jump ring, it's easiest to use two pairs of needle nose pliers. If you have one pair, you can hold one side with your fingers. If there is a gap, close it by moving the sides up and down pressing gently together. The ends should overlap then snap together tightly so the tension of the metal will hold the gap closed. When you open a jump ring (or any loop) twist it open rather than pulling it open so it will hold tight when re-closed.
