3M™ E-A-R Skull Screws Earplugs, Corded, 32 dB NRR, Gray, 120 Pairs

Make a statement with Skull Screws™. Even though the tips look as tough and rugged as threaded metal, they're made entirely of an ultra-soft, super-smooth foam. Push-to-Fit design ensures the earplugs stay clean, even when your hands or gloves are dirty. Washable and reusable (handwash with soap and water only).
