These are items I received when I stayed at a Ryokan (Japanese Inn). The size isn't specified, so I believe it's free size. The white ones are described as unisex. All three pairs have different stitching on the instep, so they are the support type. See photos 3 and 4. Upon inspection, the light blue pair has what appears to be a stain. See photo 5. The bag has not been opened, and it was like this from the beginning. It might come out if washed. They have been stored at home, and the bag has wrinkles, but the contents are clean. Please understand this before purchasing. Shipping will be via Yu-Yu Mercari.
