Hello! (I've got many other spooky things on my page if you're interested in bundling!) This is a gothic style choker necklace with some dangling spikes and a bat pendant. I'm unsure of the material. It's been worn once, and the total length is 15-16 inches long I'm open to offers, bundles, and discounts! Let me know if you have any questions! (Smoke-free & pet friendly home)
