7.9mm round double-link cable bulk jewelry chain. Approximately 3-meter (9.8 feet) rolls. Not soldered. Steel. Antiqued copper plated components are often used to give jewelry a classic and vintage look. Bulk chain makes a great base for free-form beaded chain necklaces. Use jump rings or split rings with your favorite clasp to finish the ends. Occasionally, the plastic spool is damaged in shipping. This should not affect the usability of the chain.
