How about Na Tong Phoenix Feather Shield Mask?

The Na Tong Phoenix Feather Shield Mask is OK.

The name of this mask is Feng Feng Yudun. It sounds second-rate, but it's safe, just as its name suggests. This mask is made of willow leaves, which is different from the general n95 sharp mouth. It's more comfortable to wear on your face. There is a cotton pad in it, which can not only be attached to the nose more firmly, but also won't hurt the bridge of the nose because of wearing a mask for a long time.

The medical device batch number and standard number of the mask are available, which is very suitable for this period.
