Material The foam ear plugs are manufactured from polyurethane foam that is breathable and reliable, soft and comfortable to wear, and not easy to break or fade. Design and fit Inside, the plugs feature dense microbubble cells and memory foam, which helps keep the ear canal breathable and allows the plug to conform to the shape of the ear canal for a secure, comfortable fit when worn. How to use With your forefinger and thumb, twist the earplugs into thin strips (the thinner, the better). Gently lift the ear, insert the plug, and rotate as needed to help placement. Hold the plug with your finger for about 30 seconds until it inflates to fill the ear canal. Cleaning and care Ultra soft ear plugs will get dirty with use, but they can be cleaned easily with soap and water and reused afterward.
