Your special jewelry and craft creations deserve a beautiful, high-performing wire! This copper wire is plated with a precision layer of pure silver. A non-tarnish coating is then applied over the silver plating, resulting in an incredibly shiny wire that is very soft and pliable. It can be easily formed into spiral shapes and jewelry components like chain maille, beaded chain, jump rings, ear wires and much more. Details: Silver plated18 gauge (1 mm)4 yd.
