KF94 Disposable Face Mask, 4 Layers Virus Filter Protection, Filter Efficiency ≥ 94%, Independent Packaging

Individually packed

It was one of the best mask I have been ordering. To my shock the last order, the mask has completely changed in thickness and even the imprint on N95 is missing!Reason for 2 stars is because it was good before. Otherwise 1 star for this time.
