I obtained these as prizes from Namco several years ago. I may have replaced the bags after obtaining them, but I have stored them in a dark place and haven't used them. They don't appear to have aged, but please understand that they are several years old before purchasing. I will send the four items in the photos. There are two each of Sanemi and Muichiro. Individual sales are possible at 2555 yen for two (one of each). Kimetsu no Yaiba: Muichiro Tokito, Sanemi Shinazugawa, Can Badges Demon Slayer Namco Limited Scene Anime Prize
