A double-row pegged skin membrane stretched over a longitudinal oval calabash half. The neck spike pierces the skin at four widely spaced points and runs in roughly equal parts above and below it. The double-perforated, flattened spike end rests below a small opening at the rear edge of the shell. Two strings made of twisted skin. The strings are attached to the neck with leather strap windings. The longer string is enclosed by the lower winding ring. Two pairs of small, round membrane perforations to the right and left of the exposed spit section. from Ulrich Wegner: Afrikanische Saiteninstrumente, Staatliche Museen Berlin - SPK, 1984 (Appendix Object Catalogue)
