Review (4/5): 10 masks in the box
I was unsure whether the advertised "10 pcs" meant there was one mask made of 10 different pieces of plastic and elastic, or if there were 10 masks in the package. I was pleased to see that it really does mean 10 masks.
These masks are not very sturdy. But an asthmatic can breathe with it. We tried another brand that has a softer chin holder and is sturdier, but that one smooshes the nose of the person wearing it. This mask prevents spread of droplets when speaking, and it adequately covers a cough or sneeze, while still letting a person breathe.
