Jewelry makers and crafters, stock up! This bag has 100 open jump rings (split rings) in a shiny gold finish. They're made from iron with a gold plating, and each ring has an outside diameter of 12mm – a nice, versatile size. They come open, so you just use pliers to open them wider, link them through your chain, charm, or other finding, and then close them shut again. Super useful for connecting charms to bracelets, making keychains, assembling wind chimes, or adding links to costumes. A huge bag for a small price, perfect for having plenty on hand for all your DIY projects. Note: As they're small and metal, keep them away from small children.
