Ẹgba (bracelets) are worn as part of ceremonial costumes and could be made of brass, bronze, iron, ivory or wood. The material determines the status of the individual wearing it, as the Ọba controls the use and production of brass, bronze and ivory. Ẹgba is the designation used to describe bracelets worn around the upper arm that could potentially become amulets by putting charms or medicine in them.
