These are "beoseon" (버선), traditional Korean socks. This is a set of two pairs with a floral design. They are unused. There is no size indication, but they are likely a standard adult size. They are stretchy and can be used as room socks or for warmth. Recommended for those who like Korean culture or for keeping warm. Thank you for your understanding as they have been stored at home.
