3M™ Disposable Foam Earplugs, made from slow-recovery foam, help provide a combination of comfort and hearing protection for users. Once the foam earplugs are compressed into small cylinders (rolled down), they are easy to insert into ears where the slow recovery foam expands to fit the ear canals. 3M provides a wide range of disposable foam earplugs so you can choose the best solution for your needs. 200 pairs per pack.
