I put them in a bag after checking the contents. There was a time when I displayed them indoors, but I've been storing them in a dark place for the past few years, so I'm putting them up for sale. There are no noticeable stains or folds, but they are not perfect, so please refrain from purchasing if you are concerned. Only Procellarum is complete. Six Gravity is missing Koi and Haru. There are 10 cards in total. No individual sales. I am not currently considering price reductions. Since there is some thickness when bundling all 10 cards, I plan to reinforce them with cardboard on one side. If you would like reinforcement on both sides, please let me know in the comments, and I will accommodate if possible. (I will not be able to accommodate if the thickness increases and the shipping method changes.) Please purchase only if you understand everything.
