These are 25.0cm black satin tabi socks made of 100% cotton. They are new, unused, and have been stored. Although they were unopened, I opened them for inspection because they were only sealed with a simple sticker. There was some slight yellowing on the inside (the part that touches the foot) of the white sole. I will sell them to those who understand this. - Size: 25.0 cm - Material: 100% cotton "Finest Quality Black Satin Tabi" 100% Cotton, Made in Japan 4 Kohaze (fasteners), Flannel Lining 25.0cm
