I cut the mask open and confirmed it has 3 layers. The product odor free straight out of the bag. The blown plastic mask area is a good size to cover a child's face.One star off, as the ear loops are long so I end up tying each ear loop for a good fit.I ordered these because the reviews stated they were quite small, appropriate for a toddler. The mask fell off my toddler’s face, even if I knotted the ears there was such a huge gap it was pretty much useless.The masks themselves seemed fine for short term use, I honestly haven’t used them other than the one time because of the fit but the quality was fine.I don’t see anywhere in the listing that gives dimensions so I just wanted to review for any other toddler parents out there to say wayyyyy too big for a 2 1/2 year old!I have a small face and jaw and adult masks had such a gap at the sides that I doubt they worked much. These fit much better and the different colors make it easy to tell mine from the rest of the family's. I do have the occasional ear loop break, like others have mentioned. This has only happened a few times to me though. Might be that I am more careful putting them on/taking them off as an adult compared to a child who may pull them on/off too quickly.Overall quality is much better than other similar products, nose wire is firm and close tight on my nose.Kids size (even a little too small) fits better than adult size for me. Everyone has different face size, so I shouldn't complain about it.I've ordered several of these packs in different colors. They are slightly big on my 7 year old, but a tiny knot at the end of each strap solves that. My 1st grader reports that they are very comfortable, and they last all day at school. Each mask says "Made in the USA" on the front. I will be ordering more!Bought for my granddaughter for school. She likes the color and finds them comfortable. She is in second grade and these fit her.I ordered these masks for my 2yr old grandson. The only problem I had with them is that I had to put a knot to to make it tighter to fit his. I would recommend purchasing these for your little one. It fits perfectly one is faceThe first time we bought these they were great. We had no problems with them at all. But the second order was another story. They break constantly, so instead of one a day my child is needing to use three. They don't look like the first ones, and they were packaged very differently, so either we got a different brand when we reordered, or the quality went downhill very quickly. Either way we'll find another brand next time.*""Edit*** The company contacted me immediately and kindly sent me a replacement pack of masks same day. The new ones have been just as good as the first pack we bought, so I have changed my review to 5 star, and I definitely do recommend these masks!***Second edit***I have purchased these a number of times now, with varying quality results. The most recent 2 packages of 25 each (bought at the same time for a total of 50) ALL have weak straps that easily break. My child is again averaging 3 per school day instead of just 1. Very frustrating. So basically: You're taking your chances with these. Some are great, some are not.
