Available for immediate purchase. I am not considering selling items individually. I am not very knowledgeable, so I may not be able to answer specialized questions. I received this from a friend, but I am selling it because I don't use it. It is a set of three items: YAMAHA NS110 classical guitar strings, Augustine strings, and a tuning fork. There are six Augustine strings, but please note that there are duplicate strings as shown in the third image. I am not responsible for any accidents during shipping. No returns or refunds accepted.
