Perhaps one of the most useful materials in any designer\'s stash, these versatile solid Sterling Silver Round Split Jump Rings are invaluable for a number of jewellery-making purposes and will add a quality, professional finish to your designs. Measuring 7mm in diameter, these 10 loops are a perfect all-rounder size for Chain Maille techniques as well as many other basic joining uses. Each ring has a split, allowing you to open it with two pairs of Flat Nose Pliers, gently twisting each side away from each other, rather than pulling them apart.
