3.7mm flattened drawn cable bulk jewelry chain. Approximately 3.7x7.2mm links. Approximately 10-meter (32.8 feet) rolls. Not soldered. Steel. Antiqued copper plated components are often used to give jewelry a classic and vintage look. Bulk chain by the spool makes a great base for free-form beaded chain necklaces. Many jewelry makers use jump rings or split rings with clasps to finish the ends. Occasionally, the plastic spool is damaged in shipping. This should not affect the usability of the chain.
