How to use disposable protective masks

1. Wash your hands before wearing a mask. 2. Hold the ear strap with both hands, and put the dark side on the outside (blue), and the light side on the inside (white suede). 3. Put the side of the mask with a wire (a small piece of hard) on the nose, pinch the wire according to your nose shape, and then pull the mask body completely down so that the mask completely covers the nose and nose. 4. Disposable masks are usually replaced every 8 hours and cannot be reused.
