The small lead free black pewter quatrefoil design key pendant charm hangs from a 2mm diameter black stainless steel rolo link necklace chain. It includes an easy to open/close lobster clasp. Stainless steel is a great alternative to other metals as it is very durable, does not tarnish and is great for people that have skin reactions with other metals. Your neckace will ship in a black jewelry box with a black velvet lining. Proudly made in the USA.
