3skm This is a collaboration can badge with Kushikatsu Denga. It's a can badge of Kaisei. Unused and stored in a dark place. Instant purchase is OK. I am also selling Yusei and Saki Nesu (Holo) can badges separately. If you purchase them together, I will give you a small discount, so please comment. Kaisei 3skm Kushikatsu Denga
