Metal-Detectable Earplugs
Bullet
Ribbed Cone
Good for food preparation areas, these earplugs have an enclosed ball bearing that can be sensed by metal detectors.
Roll-up plugs roll for insertion into your ear and then expand to conform to the shape of your ear canal. No-roll plugs slide right into your ear.
Ribbed plugs provide added grip that keeps plugs from backing out of your ear.
Plastic plugs are washable.
Earplugs come in individually packaged pairs. They cannot be sold outside of the United States and Canada due to product labeling requirements.
