There are many counterfeit masks
There are many counterfeit masks on the market as anyone can stamp kn95 on them, what you need to see are the numbers 2626- 2019 this tells you these are 100% legitimate, masks are of highest quality with lowest prices i have seen anywhere, shipping does take awhile as there is an urgent need for these masks, if you cant wait 2 to 3 weeks for your order i suggest you pay the extra 10 bucks for expidited shipping as you will still save money, my first order took 3 weeks to get in my hands, i showed a friend and she ordered and now has been over 2 weeks and she has not seen them yet, my second order came in 3 days so there all over the map, but still with so many orders and 1million cases of covid a day or whatever it is you can hardly expect company to keep up, just pay the extra 10 bucks bc other companies are selling masks for allot more mony, these are the best masks you can get and the price is low compared to other companies, nice tight fit, comfortable, no foging of glasses and i feel safe, no leaks, box comes with with 20 packs of 2 masks very convenient.
