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