Chest ornament, to be carried by men during dance. A piece of bone hanging from a band is supposed to start spinning during dancing, producing a "humming" sound. The chest band is broader (about 4 cm) on the chestside and more narrow (about 1 cm) on the backside. The front side has weaved in patterns of yellow and brown fibre cord. The piece of bone is attached in the middle. This bone appears to be polished and has two holes in it. The frontside of the band has a ring embedded in the cloth on either side.
