3M™ E-A-R™ Classic™ Plus Earplugs 310-1101, Uncorded, Pillow Pack, 2000 Pair/Case

3M™ E-A-R™ 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.

• SECURE: Exposed cell surface texture resists movement and helps maintain an effective seal creating a comfortable, snug noise barrier. Noise Reduction Rating (NRR) 33 dB. CSA Class AL.*
• OUTSTANDING COMFORT: This unique slow-recovery, low-pressure foam and special cylindrical shape help enhance comfort throughout the day by creating lower pressure in the ear canal
• LONGER SIZE: Classic Plus ear plugs are 20% longer than the regular E-A-R Classic ear plug (and the same diameter) to fit deeper into the ear canal and help provide higher noise reduction
• SOFT SOUND-ABSORBING FOAM: Proprietary foam is initially firm to make fitting the ear plug easier, then softens once it’s in the ear to comfortably conform to the unique shape of each ear canal
• SWEAT AND HUMIDITY RESISTANT: Classic ear plugs are resistant to moisture absorption for consistent fitting even in humid environments
• VERSATILE: Use while chipping, chiseling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing and welding
• CLEAN STORAGE: Reusable pillow pack helps keep earplugs clean when they are not being worn
• For industrial/occupational use only. Not for consumer sale or use
