Putty Buddies® Extra soft silicone means more comfort and better fit and our extra tacky texture keeps ear plugs in place for maximum effectiveness. Putty Buddies® silicone ear plugs are reusable and should be stored in the handy carrying case. Discard the ear plugs when they become dirty or lost their tackiness. Silicone ear plugs are recommended by doctors for swimming, showering and general water protection. Not recommended for diving in depths greater than 10 feet. Although Putty Buddies® are not intended for noise prevention, the user will experience a slight reduction in hearing when plugs are worn. For maximum protection, ear plugs should be worn with the Ear Band-It® head band. Please ensure all manufacturers instructions on the pack are read and understood prior to use.
