8/19/2022[Black Masks]: This is an update for the black masks. The five black masks' boxes have the Qualified Certificate [QC] statements where as the white boxes I purchased didn't. I take away one star as it only works with smaller heads as mentioned in my previous comment. I give the black masks 4 out of 5 stars. Black masks get 4 stars and white masks get 3 stars, I'm rounding up my review to four stars.8/10/2022[White Masks]: There's a statement on the side of the box that states "MFG Date/EXP Date: See Qualified Certificate [QC]." I purchased three boxes and all three boxes were missing the Qualified Certificate which has production date and shelf life. Only reason I know about it is that I purchased multiple boxes from Staples and all of their boxes had QC certificates. Regarding size, masks works well for smaller heads but too small for medium and larger-sized heads as it will pull on your ears and make them look like Sloth from Goonies. Additionally, I like that they are individually wrapped. I took away one star as it only works with smaller heads and deducted the second star as it was missing QC statements leaving it as 3 out of 5 stars.These are some of my favorite mask to order! The quality is great and quite sturdy!They fit good for us and our childrenMore color optionsI purchased a pack of these that were fantastic. I reordered them and I have no idea what has happened but this batch is horrible. They have changed the inner material and it's thin and uncomfortable. It feels like it's not going to be in any way protective. The worst part is that I just wasted $20, which is not refundable. Don't waste your money!Dumbo ears!! These would be good if the ear loops were longer. I’m disappointed with these. I buy the other masks from them with no problems
