3M E-A-R- Push-Ins Corded foam earplugs provide a comfortable option for hearing protection in the factory or manufacturing environment. They feature a blue stem on the end for easier and cleaner insertion and removal.  Each pair comes enclosed in a polybag keeping them clean and accessible as people reach in to the box for their earplugs.  The cord reduces the chances of losing your earplugs and allows the user to rest them around their neck when not in use. There are 100 pair per box.
