From the manufacturer:
12 pack of five yard spools of wire in assorted colors. Artistic Wire is permanent colored, round, light-gauge copper wire making it perfect for craft applications. It's easy to bend, yet it holds its shape to make loops and rounded bends for creating beautiful jewelry, home décor items, paper crafts, gifts, or wire beads. Artistic Wire is available in a variety of colors and gauges for everything from delicate shuttle tatting to basket weaving. Artistic Wire is resistant to scratching, peeling and marring. This is due to the special enameling process. After the enamel is applied, the wire is clear coated to prevent tarnishing.
