The expiration date is about a year, but it's in relatively good condition, without many noticeable scratches, so I think it's clean! The rubber seems to be in good condition, so I'll include it so you can use it right away, but since it has been stored at home for a long time, I recommend replacing it yourself if you are concerned. There may be oversights. Also, there may be dirt or scratches that are difficult to see in the photos, but please understand this before purchasing. I am also selling other swimming supplies. I can offer a discount for bulk purchases! If you have any questions, feel free to comment! Instant purchase is also OK!
