Size: Approximately 25cm (width) x 20cm There are signs of damage overall. I lightly tapped it, and it makes a sound. I am not knowledgeable about musical instruments, so I do not know if it produces the correct sound. I do not think I can answer technical questions. Please only purchase if you understand and agree to this. I cannot ship or reply on weekends, holidays, or public holidays. Also, I may take long breaks during summer, year-end, and New Year holidays. I will announce these on my profile each time. Please be sure to check to prevent any issues. For items with shipping included, I may change the shipping method. Please understand.
