3M™ E-A-R™ Pistonz™ Earplugs P1400, Uncorded, 400 Pair/Case

These earplug tips look like metal, but feel ultra-soft. They are made of a specially formulated foam that is so soft and comfortable the earplugs can be worn all day long. The cylindrical shape is designed to fit and seal most size ear canals. The stem is stiff enough to insert yet is designed to flex sideways if impacted during wear. No need to roll foam tips before fitting. Just grip the stem and insert tip into the ear canal — right out of the package.
