### ⭐⭐⭐⭐⭐ 







  
  
    Great masks, especially if you have a smaller face/head
  

*by N***K on Reviewed in the United States on May 3, 2021*

I have a small face/head and most masks don’t fit my face. This one is perfect! It’s comfortable and it forms a seal all around. My daughter’s face is larger and she doesn’t have as much trouble finding well fitting masks, this one is her favorite mask as well! First got a 10 pack, came back to order a 20 pack. These masks are great, especially if you have a smaller face/head like I do.

    Best myasks since Pandemic started
  

*by M***A on Reviewed in the United States on March 6, 2021*

Like most of us - we've been buying masks for over a year now. These are the best I've found. I love the fit around the nose and the fit over the cheeks and under chin. No fogging of glasses cuz the mask has a good seal. I love these and they are the only ones we wear now.  Be careful when buying as there are many similar.  Can't wait for my mother in law - (Korean) to read me the packaging. Highly reccomment.

    Total Garbage
  

*by C***A on Reviewed in the United States on October 21, 2021*

Fit is awful. when I put it on, it hung loosely from the ear straps. I could secure it around my nose with the wire, but it also hung loosely with the bottom of the mask barely below the point of my chin. When I open my mouth to talk, my chin grabs it and completely pulls the mask down and fully exposes my nose.  Totally unwearable!!!I'm a 5'1" women, yet it's both too big (width) and too small (height) at the same time.Complete waste of money.
