Jewelry makers and crafters, you’ll love these! This pack contains 230 solid copper jump rings, each measuring 18 gauge (about 0.040” or 1.0mm thick) with an outside diameter of approximately 7mm. They’re saw-cut (not machine-cut), which means the ends are clean and flat, making them much easier to open, close, and solder without big gaps. They’re made from genuine solid copper – not plated – so they have a nice, natural bright copper color that’s perfect for oxidizing, patinating, or leaving shiny. They’re lead-free and nickel-free, making them a safer choice for sensitive skin. With 230 rings in a 1-ounce pack, you have plenty for chainmaille, jewelry links, charms, keychains, decorations, or repair projects. They’re durable and made right here in the USA. A fantastic, versatile basic supply for your crafting toolkit. Open them with pliers, connect your pieces, and create something awesome!
