Since the mask is worn on the face by hanging it over the ear, if it is worn for a long time, the earring strap can compress the ear and cause pain. Therefore, in order to improve the wearing feeling of the mask, it is good to improve the material or shape of the earring strap.

In addition, since the mask for preventing droplets, which is conveniently used in an environment that requires a long period of wear, or in hot summer months or when breathing is uncomfortable, is relatively thinner than other masks such as KF80 or KF94, the earring strap of the mask easily detaches. Therefore, if the improvement is made, it will be able to get favorable response from users.
