3M E-A-R 311-1101 Classic Yellow Corded Disposable Single-Use Earplugs were the first foam earplugs ever developed. Today, they are still the leading seller across the world because of their outstanding advantages: A NRR of 29 dB, their easy-to-use cylinder shape that fits a wide range of ear canals and their soft, low-pressure foam construction for all-day wear and comfort. These earplugs are non-allergenic, moisture-resistant and non-flammable. The yellow color offers high visibility to workers and supervisors. E-A-R is the only manufacturer to make its own PVC foam, so it can regularly test for optimum and consistent performance. No wonder they have been the most requested hearing protector the world for over 30 years. Tested to ANSI S3.19-1974 Standards. 200 Pairs individually wrapped in pillow packs to a box. Sold by the box. 10 Boxes per case.
