This variety five-pack of solid copper closures includes hunkier toggle closures, along with S and J style copper closures. Made from solid copper, not electroplated, some closures have already started their patina process due to air exposure. To antique them further, use liver of sulfur. This 5 pack is an excellent deal, with each closure costing $3.60! For size reference, a quarter has a diameter of 1 inch. Ideal for chunkier necklace or bracelet designs.
