3M E-A-R Skull Screws Foam Ear Plugs (Box of 120) P1300

E-A-R Skull Screws are not your ordinary ear plugs. Their unique, steely gray finish makes them look tough as nails, but they're actually made of ultra-soft foam that offers all day comfort. 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 helps achieve an optimum noise seal. The design is also more hygienic because you never have to touch the foam with your fingers. These Skull Screws ear plugs are uncorded and have a noise reduction rating of 32 decibels (NRR 32 dB).
