17mm x 12mm Oval Twisted Link Chain Sold By The Foot CH50 features two eyelet links and one oval twisted link all held together with a 3mm rolo chain. This chain is made from solid naturally hypoallergenic brass and electroplated nickel free. This chain works especially well in necklace applications but can be used for any of your jewelry projects. We really enjoy cutting this chain apart and using the links to create earrings.
