3 pairs of corded re-usable triple flange earplugs with convenient carrying case. NRR 26. Washable is to Protect your hearing. The unique triple flanged design conforms to the shape of your ear canal giving every wearer a custom fit. The soft, pliable, translucent flanges form a triple level seal against noise. They look cool and feel great for all day comfort. These hearing protectors help reduce exposure to hazardous noise and other loud sounds. Misuse or failure to wear hearing protectors at all times that you are exposed to noise may result in hearing loss or injury. For proper use, see supervisor, User Instructions. If there is any drainage from your ear or you have an ear infection, consult with your physician before wearing ear plugs. Failure to do so may result in hearing loss or injury. Note: Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit and wearing time. It is recommended that the NRR be reduced by 50% for estimating the average amount of noise reduction provided.
