This is a 6-pack set of strings from ERNIE BALL, D'ADDARIO, and BOOMERS. All are 009-042 gauge and have been stored at home for a long time. One pack of BOOMERS has been opened, and only the 1st string is missing (see photo 2). The others are new and unopened, but we cannot guarantee their condition, so please purchase only if you understand this. We plan to ship via Yu-packet Post. Please purchase only if you agree to the above conditions. #9683l #0nes_tar
