Even though I am an adult woman and these are technically children’s sized, these masks fit me pretty well.
I have been using the regular disposable face masks from the same brand (Thinka) for a while now, and have found them to be pretty high quality. Overall I was happy with them, the only issue was the fit, as they are far too loose. I have to tie a knot in each ear loop, making the mask fit more snugly to my face. This can get annoying, and I have often wished they would make a smaller size that would fit without alteration.
So when I saw that they now offered smaller masks for children, I thought I’d try it. And they fit! Very happy with these masks.
