This is a carbon fiber mini-classic guitar. I've used it a few times, but I wasn't used to the size, so I've been storing it. It's resistant to heat, humidity, and tension, and I don't think it will warp unless it's in extreme conditions. The frets are also made of carbon, and in my subjective opinion, there's at least 98% remaining. * The strings have heavy rust and need to be replaced. * No case included. ■ Guitar Carbon Fiber ■ Nickel Hardware ■ Nut Width: 45mm ■ Scale: 500mm ■ Total Length: 78cm Outdoor Ukulele Camp Carbon Graphite Blues Thank you for looking.
