The twelve animals of the Chinese zodiac have been used as decorative motifs for well over a thousand years, and the small cast pendants are a standard format: one animal, a cord, a tassel, light enough not to swing.
All twelve signs are made. The metal is zinc alloy with a bronze-tone finish — firm and heavy for its size, but not brass and not precious metal. Because it is light and short, this is one of the easier charms to hang clear of a sightline.
