3M 7000127171 earplugs are roll-down foam earplugs with an attenuation rating of 29.0 decibels. These cylinder-shaped, small-sized earplugs provide excellent protection against noise and moisture. They are electrically insulated but not metal detectable or dielectric. With their slow-recovery foam and roll-down insertion style, they ensure a secure and comfortable fit. Although they are not reusable, each package contains 200 pairs of yellow earplugs. Unfortunately, there is no dispenser available, and they do not have any green environmental attribute or certification. Made by 3M, these earplugs are a reliable choice for hearing protection.
