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