*Ready Stock* 1 Pairs Sponge Ear Plugs Anti noise Sleep Travel Noise Canceling Soft Foam Soundproof Earplugs with case

Earplugs are designed to be placed inside the ear canal to protect the wearer from the damaging effects of excessive noise, or to block the entrance of water, wind, dirt or debris. How to use: Insert memory foam earplugs by holding the plug between your thumb and index finger. Squeeze the earplug and roll it between the two digits, compressing the foam. Place the earplug into your ear canal. As the foam begins to expand, it will conform to the shape of your ear, sealing the canal and blocking out or muffling surrounding noises. Keep the earplug from pushing out of the canal as it expands by applying light pressure on the end for 30 seconds or so.
