This was created to allow more people to enjoy the Bamboo Sax, which takes time to manufacture. The material is a type of ABS resin (the same material as a clarinet) that is not easily affected by humidity or temperature. It features consistent quality and ease of handling, with a bright and crisp tone♪ It's in the key of C (C major). 【Total Length】32cm 【Maximum Diameter】Approx. 3cm 【Weight】Approx. 200g 【Included】Reed (tenor 1/2), ligature, cap, instruction manual (fingering chart) I only played it once, then cleaned it and put it away.
