These are Ichika Hoshino from Project Sekai's Leo/need unit's badges and clips. The badge features artwork from the 2024 Creators Festa (Niconico Super Conference), and the clip features artwork from the Sanrio collaboration gacha. I displayed them for a few days after obtaining them, but have since stored them in a dark place. There are no noticeable scratches or stains, but please understand that these items have been stored and inspected by an amateur before purchasing.
