Size: Approximately 67cm in length, 8cm in width. Signs of age-related deterioration are visible. The instrument has not been played. I am not knowledgeable about musical instruments, so I do not know if it will produce an accurate sound. I do not believe I can answer technical questions. I am unable to ship or respond on weekends and holidays. Additionally, I may take extended breaks during summer, year-end, and New Year holidays. Please check my profile for announcements regarding these periods. To prevent any issues, please be sure to check. For items with shipping included, I may change the shipping method. Thank you for your understanding.
