Skull Screws(TM) Earplugs, grab attention with their edgy threaded metal look, but feel soft and comfortable to encourage hearing protection compliance among workers where hearing protection is required. There is no need to roll down the foam before inserting in ears. Simply pinch the insertion stem between fingers and push to fit, which keeps the tip going into the ears clean even if hands are somewhat soiled with dirt, oil, grease, or some other contaminant.
