Chain Maille supplies - Anodised Aluminium jump rings 18 ga, 3/16" or 4.76mm (our ref H18). We supply in packs of 100. This riotous colour mix is called Multi, and uses every colour we have! We use these rings in our Byzantine Triple kit, but they can also be used in many other weaves. Two packets are needed to make an adult size byzantine weave bracelet.
