Size: 4-5, XS size (20.0 - 22.0cm) The expiration date is about a year, but Since there are relatively few noticeable scratches, I think it's in good condition! There may be oversights. Also, there may be stains or scratches that are difficult to see in the photos, Please purchase if you understand. I also have swimming supplies for sale. For bulk purchases, I can offer a discount, but it's a small one! If you have any questions, feel free to comment! Instant purchase is also OK!
