The materials used have sufficient strength and can not be damaged or deformed during normal service life. Ÿ The design of the headband is adjustable for easy wearing and removal, the mask is able to be firmly fixed on the face and there will be no obvious compression or tenderness problems when wearing.The mask should be able to ensure close contact with the face, and should not deform during the service life.
