I had ordered KN95 masks in Black from this seller previously and was very happy with them. When it was time for more, I saw these in a rainbow of colors. As a fashion-conscious person, these are perfect. The fit is great for both me (smaller face) and my husband (larger face). I typically double loop the ear strap for a tighter fit and found the straps very secure and none of them have come apart. The colors are great, and I love that I can coordinate with the outfit of the day. My only complaint there was that the dye on the purple were a little splotchy but nothing overly dramatic. While I am not overly concerned about particles leaking through, I did read a review stating these masks do not hold water. I tested mine and filled with water, and no leakage, even after a few minutes.Bottom-line: I am very happy with the quality and price.• If I could make one suggestion, I would love it if the inside were black, so my makeup does not show all over the inside.
