3.7mm flattened drawn cable bulk jewelry chain. Approximately 3.7x7.2mm links. Approximately 10-meter (32.8 feet) rolls. Not soldered. Steel. The warm look of brass plated chain works great for all-purpose designs. Bulk chain by the spool makes a great base for free-form beaded chain necklaces. Use jump rings or split rings with your favorite clasp to finish the ends. Stock up on spools so that whenever your muse calls, you've got the supplies you need! Occasionally, the plastic spool is damaged in shipping. This should not affect the usability of the chain.
