This is a little lot of 4 Demon Slayer Kimetsu no Yaiba keychains. They are all between 2 and 2.5 inches. For the materials, 3 are acrylic and then 1 is like a sort of wood. They are all for Nezuko and Tanjiro Kamado. The key chains have actually never been used as keychains or key dangles from me, they were just displayed in a smoke free home for years then put in storage for a few more years (still a smoke free home) until now. Feel free to offer or ask any questions you may have.
