I am selling this item to organize my collection. Diver's cards often have white spots on the back from the time they are produced. This card also has a chip on the top of the back. Please check the photos carefully before purchasing. I have kept the card in a sleeve immediately after it was produced, but if you are looking for a perfect item for your collection, please refrain from purchasing to avoid any trouble. Returns and exchanges after shipping are not possible to prevent any swapping. Shipping: It will be shipped via Yu-Packet Post Mini. The card will be reinforced with a sleeve and cardboard, and packaged to be waterproof. I will only provide minimal support for any shipping issues. Please contact the shipping company or Mercari's administration for any loss or damage during delivery. Cancellations, compensation, refunds, or resends are not possible due to shipping issues. Thank you!
