This is a KUN shoulder rest for violin. I bought it new about 5 years ago and used it once or twice, but I've been storing it since I got another shoulder rest that I liked better. Please refrain from purchasing if you are sensitive to minor details or are overly concerned about imperfections. It will be disassembled for shipping. The screws on the feet are different lengths for the left and right sides, so please check them when assembling. Thank you for your understanding that this is a used item and has been stored at home.
