Peltor® NEXT™, Skull Screws are the first and only hearing protection brand developed specifically for younger workers.  Skull Screws are no ordinary earplugs.  Their unique, steely gray finish makes them look tough as nails, but they are actually made of ultra-soft foam that offers all day comfort.  Add some high impact packaging graphics, and now you’ve got a radical new look that meets the styles and attitude that appeals to younger workers.  The Skull Screws aren’t just about their looks either. The convenience of a no-roll down plug is further advanced with the addition of screw “threads” that are molded into the foam. Twisting the plug during insertion can help achieve an optimum noise seal.  The tough look also comes with a tough NRR 30dB protection.  Contains 120  Skull Screws per box.
