T-shaped Helps reduce noise Disposable 30 dB noise reduction rating. Soft, comfortable design to use while sleeping. 100% satisfaction guaranteed With clean hands, free from hand creams and lotions, slowly roll down and squeeze the earplug between your fingers until it is compressed. Insert the compressed plug slowly into the ear canal. This is easier if the ear is gently pulled upward and out. Keep the plug in place until it has expanded back to fill the ear canal. Refit the plug if it becomes dislodged through movement. Before each fitting, the plugs should be inspected. Do not use dirty or damaged plugs. © 2018 Walgreen Co.
