These are long Familia socks. They are white socks, but there are stains that won't come out even after washing due to use. They measure 15 cm when laid flat, so I think they are socks for 17 cm feet. The photo with the ruler shows two of the other items I'm selling, with different sizes, stacked together. Please understand that these are used items. I will basically use recycled materials for packaging. If you have any questions, please ask and message me until you are satisfied. I will ship using either Yu-Yu Mercari Bin or Raku-Raku Mercari Bin, whichever can ship faster.
