The unique pod design of the 3M™ E-A-R™ Express Earplug allows the foam to compress easily so that the plug slides gently into the ear and expands slowly, making an effective seal for most ear canals. The 3M™ E-A-R™ Express Earplug has an insertion grip which makes handling and fitting the earplug easier and more hygienic. Available with a cord. Box of 100 pairs
