Make a statement with Skull Screws™. Even though the threaded tips look as tough and rugged as heavy metal, they're made entirely of an ultra-soft foam to provide you with a stylish yet very comfortable hearing-protection option. Push-to-Fit design ensures the earplugs stay clean, even when your hands or gloves are dirty. Unique, nut-and-bolt-inspired stem grips allow you to insert and remove your earplugs without touching the foam plugs themselves. Ultra-soft, no-roll foam quickly adjusts to the shape of the ear canal to help create an excellent noise-reducing seal. Skull Screws™ are washable and reusable (handwash with soap and water only). Compatible with the 3M™ E-A-Rfit™ Dual-Ear Validation System-E-A-Rfit™ provides an accurate quantitative assessment of exactly how much noise-reduction a hearing protector will provide to any given worker.
