This fine pair of anklets (which could now be worn as bracelets) are of pierced brass. They do not open but instead were designed to slip over the feet.
Hoek (2004, p. 139) illustrates a related pair, as does Jain-Neubauer (200, p. 44).
The two are in excellent condition and have obvious age. They are decorative and sculptural.
