The 3M™ E-A-R™ UltraFit™ Earplugs are made with a triple-flange design to help contour to the different shapes and sizes of ear canals. This helps create a noise-blocking seal. Workers can insert the triple flanged ear tips easily into their ears by holding the stem and pushing the ear tips into the ears. Pliable material can be washed and reused, cutting down costs and extending the hearing protector's life. Comes with a carrying case to help keep the earplugs clean and accessible for re-use.
