Eleven strips of string [are] detached from the epidermis between the two pierced bamboo nodes. Under each string [are] two bars of different heights (pieces of bark from a palm leaf stalk). Where the strings have grown together with the epidermis, the tube is wrapped four times with twisted plant material, the ends of which are knotted together.
