1 metre of base metal bright silver coloured twisted loop mother & son chain. This unusual chain is comprised of one larger link, followed by a smaller link and is known as mother and son chain. Larger link length: 6.5mm, link width: 3.9mm (x 0.4mm thick), smaller link length: 3.4mm, link width: 2mm (x 0.5mm thick), total length of the two links is approximately 8.3mm. The core of this chain has been made primarily from brass. These links have been soldered shut, making them secure despite their thickness. Use wire cutters to cut the chain apart to join it to components. The bigger links in this chain are quite large, so jump rings will easily hook into them.
