These are used zori (sandals), worn twice. They are black zori with straps in two colors: ocher and red. They were purchased from a kimono shop with a 205-year history. I think they are relatively clean. The size is about 23cm. I usually wear sneakers in sizes 22.5-23cm. These have their own box, but they will be shipped in a Takkyubin Compact or Yu-Packet Plus box!
