From Funko. Funko POP! Pins aren't your typical pins! These collectible pins come in all sorts of metal finishes, with unique techniques to help push the boundaries of what a pin typically is. Each pin features Funko's signature style and a removable display stand to showcase your pin when you're not wearing it! Each pin stands about 3 3/4' tall and comes packaged in a window box. Choose from some of your favorite Demon Slayer characters!
