By using "polyethylene terephthalate," a type of plastic, for the body of the sanshin, this sanshin is resistant to heat and rain, which are weaknesses of traditional sanshin made with genuine or artificial leather. (Made by Urumaya, an Okinawan sanshin shop) Because the surface is stretched with strong pressure, the sanshin's tone has a good sustain, producing a clear, high-pitched sound. Furthermore, photos and illustrations can be applied to this surface. *The tuning pegs (karakui) are "Modoran Karakui" made by Urumaya. "Modoran Karakui" is an innovative product that makes tuning the sanshin, which can be difficult for beginners, easy. Once installed, you can tune with one hand, and the strings will not unwind. When shipped, it will be sent in a cardboard box. (A case is not included.) A pick made by the sanshin shop "Urumaya" is also included. (Standard size, 80cm in total length) *If you would like to hear the sound of the sanshin, please search for "Urumaya + Doremi de Sanshin" on YouTube and listen to the video. Type...Sanshin
