The workmanship is very good. The mask is soft, comfortable to wear and elastic! I think the anti haze effect is good. And it's fresh. It is light, thin and comfortable. It fits the face completely. Behind the ears, the super breathable belt will not feel uncomfortable on the face at all. It will be worn when you go out. It is very breathable and the quality meets my requirements. Moreover, the price is so affordable and the quality of the mask is very good.
