Ẹkpoki were often made by the Isekpokin from leather, however the Igun Ẹronmwon made some from bronze. They would have been used to carry precious and important objects to the Ọba and, according to oral tradition, the heads of conquered enemies, soil taken from conquered lands and beads. Ẹkpoki may also have been used for the storage of the Ọba’s ceremonial clothes.
