YAMAHA P-28 metronome. Made by Nippon Gakki. I tried to wind the mainspring, but it was stiff and wouldn't turn. Since I can't confirm its operation, I'm selling it as junk. The outer box has scratches and stains due to age. Please consider it for repair, parts, or collection purposes. Due to it being a junk item, returns and refunds are not accepted. Please check the condition in the photos.
