I purchased this a year ago. The first cards, No. 1, 2, and 4, have some wrinkles and creases as shown in photos 8-12, but the rest are in good condition because I was the only one who handled them, and I used a flash. The blank cards and word list are slightly bent at the edges, as shown in photos 5 and 7. All contents, including the word list and blank cards, are complete, and I have confirmed that there are no missing cards. The pink box for storing the cards was only used to take the cards out initially, and they were immediately stored in the A and B boxes. The box itself was also stored in a dark place. I usually stored the cards in a separate case to prevent them from bending. I used box A more frequently, and box B was not used as much, so I don't think there is much wear and tear. However, both were used for about 2-3 months. This is a set sale. I think you can still use them, so if you are interested, please consider purchasing them while they are still in good condition.
