This is a set of strings for a Brazilian-made flat mandolin. A pick is included as a bonus. I am not familiar with the details of the contents, so I cannot answer any detailed questions. Please be aware of this. It has been stored at home, and the outer packaging has some damage due to age. The contents are unopened, but each string is sealed in plastic, so it is believed that there is no metal rust. ⭐︎ Flat Mandolin String Set Two each of Mi, La, Re, and So, for a total of 4 pairs in a set Rouxinol ⭐︎ Unopened and unused ⭐︎ Includes a bonus pick ⭐︎ Made in Brazil ⭐︎ We do not accept requests for price reductions. Please be aware of this.
