I still hang my amulet by a black cord, because unlike chains, cording does not have links that can break. These amulets were made by Buddhist Monks in Thailand, cast in iron, from amulets HUNDREDS of years old. We have both Sitting Buddha and Walking Buddha (walking Bhuddas are quite unusual), and the image is depicted on both sides. The image is surrounded by a band of brass. Each amulet is strung on a black silk cord, and is contained in beautiful little pouch.
