Anodised Aluminium jump rings 20 ga, 1/16" or 3.17mm (our ref D20). We supply in packs of 100. This happy colour mix is called Rock On - a mix of pink, purple, black and silver. We use these rings in our Turning Japanese kit (see additional photo), but they can also be used in many other weaves. You will need 2 packets of these plus 1 packet H18 in silver to make the Turning Japanese bracelet and earring set.
