Moldex 6420 Rockets are washable and reusable. They are designed with an easy grip handle so they can be easily placed in the ear canal. Flexible flanges are able to fit most size ear canals, and the air bubble in the tip provides cushioned comfort that workers won’t mind wearing. These earplugs come with a convenient Pocket-Pak carry case for hygienic storage when the earplugs are not being worn. Also brightly colored for easy safety compliance checks. Moldex Rockets are NRR 27 and feature a new sound dampening additive.
