Unopened. Size: M. Since the initial packaging does not have individual wrapping, there may be some fine dust. Please purchase if you understand this. Since it is unopened, I cannot guarantee against initial defects, so please understand. Although unopened, it has been stored, so please refrain from purchasing if you are sensitive to this. I am also selling Uniqlo Heattech, Airism, and other items. Please take a look. #shimauniqlo
