Purchased new in September 2025. Used for about two months, practicing about once a week. Selling as I no longer use it. Will ship without the original box, with parts disassembled. This is the standard model shoulder rest for violin, the "Original" by KUN, a product loved worldwide. The size is for 4/4 (full size) violins. It's simple, durable, and a standard product that can be used by beginners to advanced players.
