Bests & Worsts Reviews from Amazon

I run a small pediatric office in Orlando, and found these masks on Amazon recently. They come in at a little over a dollar per - much cheaper than the going rate of $20 for ea mask that scalpers have been selling. They look good to me, but in light of the recent fraudulent products that have plagues hospitals in the PNW, and in order to keep my staff safe, I decided to ask 3M about them and sent them hi-res images. I am awaiting a response from them, but suspect that they will be unable to tell me one way or another if they are authentic 3M masks. I will assume they are authentic, as it was fulfilled by Amazon, and not a third party. I will update with 3M's response, but for the time being, they seem legit.
