Ergonomically pre-shaped for comfort and fit, these Uvex X-Fit disposable earplugs feature an X-shaped embossing which helps reduce the level of pressure created inside the ear canals. It also helps to improve grip and makes it easier to remove the plugs from the ears when necessary. Supplied as a dispenser refill pack of 300 pairs, these high-attenuating earplugs are suitable for use in high-noise areas.
