I ordered 100 Chengde KN95 mask but they were out of stock. I was notified that they can be replaced with more expensive Powcom masks. I agreed but in the end, I received 100 Zhong JianLe masks. I googled, it also has good quality so I am fine with that. It fits my husband's face perfectly and he likes it pretty much. A little big for me, but overall I think it is worth purchasing. I also received one additional mask storage case and one additional bag of KN95 masks. I did not order them, I think they are given to me as a gift. The seller is very generous. Great product, great purchase.
