How to wear a disposable mask?

One: Disposable mask, with dark color on the front and outward, with metal strip inside and nose clip.

Two: the reverse side of the disposable mask is lighter, and the reverse side faces inward, indicating that the light side is close to our face. In addition, it should be noted that the end with the metal strip is above the mask, so don't buckle the strap backwards.

Three: after distinguishing the front, back, top and bottom of the mask, wash your hands to ensure that the light-colored side of the mask faces inward (back), and the end with metal strips faces upward (top), and hang the ropes at both ends on your ears.

Four: press the metal strips on both sides of the bridge of the nose with both hands to make the upper end of the mask close to the bridge of the nose. Then stretch the mask downward so that the mask does not wrinkle and better covers the nose and mouth.
