These are RONI loose socks. They are children's clothing, but are for sizes 22-24cm, so if the size fits, I think high school students and adults can wear them. Unused and unopened, but they have been stored at home for several years after purchase. I feel that the opening part is slightly discolored by the sun. (It may be this color originally) Thank you. - No price reduction. - There are no discounts for bulk purchases. - No reservations or holds. - Shipping method cannot be changed. - Since I have packed the item after listing it, I cannot take measurements or add more pictures. - Please purchase only if you can smoothly evaluate the item after receiving it. - I will block those who do not respond to comments.
