The depth of the shell material can be seen from where it has been cut into an almond shape. The convex surface varies from red to a more pale red in contrast to its concave interior. The interior features a transparent white layer where the red shell material can be seen beneath. A circular perforation has been drilled into one end of the almond shaped ornament. A two-ply braid of dark brown human hair has been threaded through the circular perforation to form a neck band. Sometimes te kora (coconut sennit fibre cordage) might be used. It would be worn around the neck, placed above the bunna (throat ornament of human hair) and worn mostly by men. The koikoinanti can also be referred to as 'the small shell of the spirits' and is regarded a highly valuable possesion.
