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 the sealing ability and improves wearer comfort. Pre-molded silicone will not deteriorate like similar earplugs made of plastic. Helps prevent the swimmer's ear and the surfer's ear. Washable and reusable for extended wear. Includes storage case. Directions Reach overhead 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 plugin too far 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. Earplugs should be inspected regularly for serviceability. Replace hard, torn, or deformed earplugs.
