The Moldex 6400 Rockets now come with a new sound dampening additive and an independently tested NRR 27. The earplugs have an easy grip handle and flexible triple flange design to make fitting them quick and easy. Every pair comes with a matching Pocket-Pak carry case for hygienic storage. It prevents having to store the uncorded earplugs in dirty pockets during breaks, or the risk of setting them down and losing them. The bright green color can be easily seen when checking for safety compliance. Reuse these environmentally friendly earplugs and reduce costs easily by washing them.
