OTO-OTO DT1S NTS Mini Acoustic Guitar It produces a surprisingly full sound for its size. It's fun for casual playing at campsites, outdoors, or gatherings. Please check the official website for specifications. String height at 12th fret: 6th string 2.8mm, 1st string 2.2mm The bulge on the back of the body seems to be a design feature. The strings are old, but will be shipped as is. There is a dent on the lower part of the body (photo 7). There are no other noticeable scratches, but there may be minor ones. Please refrain from purchasing if you are looking for a perfect condition item. There is almost no fret wear. A genuine, backpack-style soft case is included. Feel free to ask any questions. *I have a cat. There may be some hair that I couldn't remove, so please refrain from purchasing if you have allergies or are concerned about this.*
