This is a can badge of Hoshino Ichika from Project Sekai's Leo/need. The design is from the 2024 Creators Festa (Nico Nico Super Conference), and the flower-like parts in the background are sparkly. I had it attached to my bag for a few days after I got it, but I've kept it in a dark place since then. There are no noticeable scratches or stains, but please understand that this is a personal item and has been inspected by an amateur. Immediate purchase is OK. For those who are fans of Hoshino Ichika, how about it?
