1 metre of base metal bronze coloured twisted oval loop chain, link length: 7mm, link width: 5.1mm (x 0.9mm thick). The core of this chain has been made primarily from iron, with a brass surface coating. These links have been lightly soldered shut, making them quite secure. Use wire cutters to cut the chain apart to join it to components, alternatively, use two pairs of pliers to break the seal (it has only been lightly soldered). The links in this chain are quite large, so jump rings will easily hook into them.
