As the wearing of masks is becoming a daily necessity and becoming a necessity, the importance of not only mask performance but also the wearing comfort of the mask is emerging. Since the mask is worn on the face by hanging over the ear, wearing it for a long time can cause the earring string to press on the ear and cause pain. Therefore, in order to improve the wearing comfort of the mask, it is good if the material or shape of the earring string is improved.

In addition, the droplet blocking mask, which is conveniently used in an environment where the mask has to be worn for a long time, in hot summer or when breathing is difficult, is relatively thin compared to other masks such as KF80 or KF94, so the earring strap of the mask comes off easily. Therefore, if the improvement is made, it will be well received by users.
