This is a SEGA-made Aime card (illustration of Decisive Battle Zuikaku) exchanged during the Kantai Collection Arcade year-end campaign in 2025. The blue envelope in the background will also be included. It will be shipped with cardboard reinforcement to prevent bending and a waterproof vinyl sheet. Since it is unused, I have not included a photo of the back with the serial code. If you would like to see the photo, please request it in the comments. In that case, the serial number area will be blacked out.
