Haven’t used them yet but but they appear to be of quality construction.
Miima KF94 Adult-Medium(Black)
These masks fit my 14 year old granddaughter (who has a small face) perfectly. I’ve ordered a variety of masks from Kollecte and they are a fantastic company to deal with. They have excellent email customer service who go out of their way to be helpful. Once I ordered some while masks because they were out of black, then I emailed asking them to let me know when the black came in since I preferred that color. The representative replied in short order, that they had just received black ones and went ahead and swapped them out for me! Their shipping us also really fast, I received my latest order in 3 days. I recommend them highly.
Bluna Facefit KF94 Black-Adjustable(Adult)
