Mack's AquaBlock Earplugs, 2 Pair, Comfortable, Waterproof, Ear Plugs for Swimming, Snorkeling and Showering (Pack of 4)

Pre-molded flanged earplugs constructed of silicone and designed for super soft, super comfortable, waterproof protection. Unique flex stem and triple flange design allow for a more customized fit, which increases sealing ability and improves wearer comfort. Pre-molded silicone will not deteriorate like similar earplugs made of plastic. Includes storage case. Directions, Reach over the head and gently pull up and back on the outer ear to straighten the ear canal. Push and twist the plug into the ear to form an airtight seal. Be careful not to push the plug in too far so that you are unable to easily grasp it with your thumb and forefinger. To remove, grasp the earplug stem with thumb and forefinger and remove slowly with a twisting motion to gradually break the seal. Cleaning instructions: Wash with mild soap and warm water. Dry thoroughly before reinserting into the ear. Store in original case. Discard if earplugs come in contact with lubricants, solvents, or other chemicals. If used daily, replace every 2 to 4 weeks. Mack's Aquablock earplugs are safe for use in salt and chlorinated water. Earplugs should be inspected regularly for serviceability. If they become hard, torn, or deformed, they should be replaced. Mack's aqua block pre-molded flanged earplugs are designed for ultra-soft, ultra-comfortable, water protection.
