Expensive but good
Yes... $200 for a box of ten 8511 masks is crazy. But, that real 3M valve makes all the difference for breathability. I received my order for one box within a few days, and they all appear to be completely genuine 100% 3M branded packaging and product. If this saves your health and your life, it becomes worth it.
