E-A-R Classic Earplugs (200 Pair Pillow Pack) Uncorded – 3M 310-1001

Description 3M EAR Classic Earplugs have set the industry standard for noise reduction as the world’s first foam earplugs. These earplugs are made of a proprietary soft energy-absorbing slow-recovery foam that’s designed to conform to the shape of the ear canal to help provide hearing protection.  Sold in pairs of 200 / box. This earplug’s moisture resistant foam is initially firm to make fitting the earplug easier, softening once it’s in the ear to comfortably expand and conform to the shape of each ear canal. The slow recovery feature helps with earplug insertion by giving the user time to get the compressed foam cylinder (rolled down earplug) into the ear before the foam fully expands. Per-pair packaging options include a pillow pack that can be used to store earplugs between uses. Pillow pack option for storage of earplugs between uses Test Compatible with 3M™ E-A-Rift™ Validation System CSA Class AL Uncorded Individually packed Noise Reduction Rating (NRR): 29 dB.
