An elongated bowl with broad, tapered narrow edges, towards which the base of the bowl curves upwards. The long edges curve slightly over the opening. On each narrow side [are] six diagonally burnt string guide perforations. Six strings. One stem extension carved lengthwise. Four round perforations arranged in a square in the centre of the bottom of the bowl and eight impressions in the wood in the centre line. A firmly bound cushion ring wrapped with strips of fabric around the edge of the open-topped resonance calabash. This [is] also tied to the shell through two shell perforations by means of a string made of thick vegetable material. One end of the string [is] tied to a crosspiece below a perforation, the other end [is] probably not original. A linear notched pattern along the narrow edges. from Ulrich Wegner: Afrikanische Saiteninstrumente, Staatliche Museen Berlin - SPK, 1984 (Appendix Object Catalogue)
