It fits comfortably because it fits your face. If it is a bellows mask it will break up as soon as a rash will be made, but this mask will not rub so be safe! Although mouth breathing will cause water droplets to accumulate, if you breathe through your nose you can use it without exchanging one a day.
It is a stereoscopic type to fit on the face so it is not stuffy than the pleated mask. I like the way it looks and refreshing. Since it is individual packaging no matter what, it is hygienic and is very convenient to carry.
Masks are individually packaged one by one, and they are very handy for carrying. Because it is a three-dimensional shape, the mouth is easy, but it is somewhat interesting to have gaps on both sides of the nose. In this respect, the type mask with nose fitter is excellent. It is regrettable that the ear can easily be peeled off by quality. There were many individuals who could peel off just by pulling the ear strap lightly for wearing the mask.
