These Pavé Rhinestone Fluorescent Neon Headphone Cat Ears are made from 3mm cast acrylic which is laser engraved (each rhinestone circle) and laser cut. They are attached with Heavy Duty Velcro (Black) to your Headphones. Each Rhinestone is hand placed and glued. We engrave each Rhinestone circle so the Rhinestones sit just below the surface of the acrylic to ensure the Rhinestones will not come off during normal wear. Even the Fluorescent Neon Rhinestones GLOW IN BLACKLIGHT! Larger than ALL our other Cat Ears!!! See the size in our photos.
