Composed of pure copper wire plated with 99.9% silver with a baked-on clear coating to prevent tarnishing. Provides the look of silver at a fraction of the cost. Use it in your wire wrapping projects or to make jump rings and ear wires. Also suitable for bead stringing. Provided on plastic spools (except for the 14 and 16 gauge sizes) and available in a wide range of diameters.
