A wooden bowl, transversely oval in outline, only slightly convex towards the long sides. A skin cover partially detached from the rim of the bowl, stretched over the outside of the bowl by a few unevenly thick skin straps. The straps are only fragmentary and are still attached to the cover skin at one point. Parallel longitudinal arms resting on the rear edge of the shell below the lid. Ball rings binding the upper ends of the seven strings of twisted plant fibre together with old string material (?). Four of the string ends are tied to a common crosspiece on the outside of the lower bowl wall, while the three remaining string ends are wrapped around the string strand above the crosspiece. A small, round perforation in the centre of the shell body. Two round membrane openings to the left and right of the longitudinal bar passage. Twelve small openings in the top of the skin, arranged in a rhombus. from Ulrich Wegner: Afrikanische Saiteninstrumente, Staatliche Museen Berlin - SPK, 1984 (Appendix Object Catalogue)
