They are as described. This disposable mask is exactly what I was looking for.They do fit, and the nose bridge looks stronger, which reduces upward breathing. Connect the earrings correctly and be the same size, wear them all day without any problems The mask is a good size adult disposable mask with nose pinch for a good fit. The mask expands to fully cover your nose and chin and conforms perfectly to fit the face. The ear loops are decent. The Bag is sealed well for preventing accidental contamination. A great product with great price.Mask are beautiful just what I was looking for and you can breathe in them I will be using these at the gym. These just look much better than the disposable blue masks I hate those feel like I'm in a hospital. It perfect and exactly what I was looking for fits your face too, not too small or too large just right for me. Finally a company with good quality masks and the best part is that you get high efficient masks!!! Will buy more again! [Go to full review]

Fail Suspicious Reviewers
Take-Back Reviewers
4 of the 29 reviewers have had at least one of their past reviews for another product deleted. The Take-Back Reviewers have rated this product an average of 5.0 while the reviewers who don't have any deleted reviews in their history have rated this product an average of 3.4. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
Warn Rating Trend
-
- 14%
- Created over 1 day
We counted 29 reviews for this product over the span of 73 days, an average of 0.4 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 3 or fewer reviews on any given day.
However, we see the following 1 day exceeding this threshold:In total, we found that 4 reviews were created on just 1 day. Although any days with a larger number of reviews than expected is suspicious, these reviews do not appear to have a significant impact on the overall rating.

There are a few limitations to keep in mind regarding the Deleted Reviews test:
There are a few limitations to keep in mind regarding the Deleted Reviews test:
- We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
- We have no information on reviews that were never published in the first place.
- We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.
