The Quintessential Quintuplets Complete Set, including volumes 12-14 which are new and unopened, plus a Yotsuba fanbook. Since I often read digitally, some volumes are unopened. I purchased all volumes new. Volumes 3-11 are first editions, and volumes 12-14 were also purchased at the time, so they may be first editions, but I can't confirm since they are unopened. They have been stored in a dark place, but please understand that there may be some yellowing or staining due to aging. Immediate purchase is welcome.
