3M E-A-R Classic Soft Earplugs are made of soft foam, as the foam warms to the body temperature, it becomes softer and shapes to the individual's ear canal. This 'shaping' allows the earplugs to form an excellent seal against noise, and as time goes on, the foam continues to soften for added comfort.
Compatible with the 3M One-Touch Dispenser (sold separately).
- Textured surface helps keep earplugs in place
