EarPlug 3M EX-01-002
3M ™ E-A-R ™ Express Earplugs EX-01-002 have a unique design that makes the foam easily compressed and the plug is easy to insert into the ear. When the plug is in place, the foam expands slowly until it seals the ear canal (this plug fits almost all ear canals). The shaft facilitates insertion and removal of the plug. Also available with twist (without twist in this version).
