This is a tuning fork from Kyorin Corporation. It's an old item, I've had it for about 15 years. The case and backing card show their age, so please refrain from purchasing if you are concerned. There are no noticeable scratches or stains on the main body, but I apologize if I missed anything. It will be packaged with bubble wrap. Please read my profile before purchasing (*^^*) Tuning fork, tuner, musical instrument, guitar, bass, drums, keyboard, band, electric, classical, tuning
