This is a panpipe, a folk instrument from the Andes region of South America. The longest pipe is approximately 16.5cm. It has 13 pipes. This item was received as a paid sample, and I am listing it here. I checked the tuning, and it is not good. It cannot be used for performance. It does produce sound. It's about the level of a toy. It might be good for practicing how to play. For shipping, I will use Yamato Transport home delivery service. Folk music, traditional instrument, Inca, Cusco
