We plan to ship with cardboard reinforcement on one side, but you can upgrade to a hard case for an additional 50 yen. If you don't specify, you are welcome to purchase immediately. I handle cards I pulled myself with gloves and immediately store them in sleeves, but I am not a professional, so please refrain from purchasing if you are concerned. Also, the cards may include trade items, so please refrain from purchasing if you are sensitive to this. Due to the above, cancellations and changes are not possible after purchase.
