The reason is on me. This is a set of 26 Yoito Yoshizawa's photos + 1 sticker. After opening, I stored them in the provided bag. Therefore, some photos have slightly bent when separating them because they stuck together. It's difficult to see, but please take a good look at the photos before purchasing. I will put them in the provided bag, reinforce them with cardboard to prevent bending, and ship them. However, please understand that I am an amateur.
