The mask should be kept horizontal, not vertical.
Some feel confused. Why most of the facial masks are displayed in the vertical way? "Vertical displaying" is to let the consumers have a more intuitive impression to do the selective purchasing action.
But for the daily storing, the facial mask is to be kept horizontal in storage shelves, which is helpful for the face paper to absorb the essence. If the facial mask is to be kept vertical for the long time, the essence will be affected by the gravity and deposit in the bottom of the packing bag. All causes that the essence distributes unevenly in the face paper and the customers could not have good using experience and feeling.
At the same time, the facial mask should also be kept away from the sunlight, the too high or too low temperature and the wet place.
