Regarding Operation Confirmation: I performed an initial operation check up to the starting point on my own console just before listing the item, but I cannot guarantee operation due to compatibility issues with different readers. I have not checked the internal battery. As shown in the images, there are some scratches. The item will be shipped via Yu-Packet Post and a cushioning sheet bag. Please understand that this is a used item before considering a purchase. Returns, refunds, and exchanges are not accepted.
