I put it in a sleeve, then in a card case, and store it in a dark place. Upon personal inspection, it is generally clean. Please check the photos and purchase. If you want to check any other specific areas, please send me a message and I will add more photos. I will reinforce measures against water damage and folding. It comes with a sleeve and a card case. I will basically ship via regular mail. If you prefer Mercari delivery or Letter Pack, it is possible to change it, but there will be an additional charge. Combined shipping is also possible, so if you send me a message, I will create a dedicated listing. You can also purchase directly without any comments.
