The shells are small in size, feature a short spire, long belly and aperture and are black and off-white striped in colour. They have been threaded onto the waist band in two horizonal rows with the spires directed towards the edge. One end of te taona n riri has been finished with a woven end where the two ends of kora have been left loose. The other end has been knotted into a stub of te kora and te ira. Te taona n riri would be worn across the waist, atop te riri (skirt) and below another waist ornament made of te nana (coconut shell discs) for dance ceremonies by women.
