Review (2/5): Hot Purple 3 pack from e-Factory NY 5 stars.  Deep Green 1 pack from Yolo Studio 1 Star
Received as expected. Nicely packed. Lightweight and good quality. Used it today for more than an hour and had no issue with it. Look cool and feel breathable and comfortable. May order more.
Update: from 5 star to 2 star rating 12/17/20:
After 5 star experience with the "Hot Purple 3 Pack (sold by e-Factory NY)", I decided to buy the Deep Green 1 Pack. I didn't realize this one pack's seller is "Yolo Studio" until I was shocked by the totally opposite experience.
Both purchases were Prime shipped by Amazon so both arrived pretty quick but that was the only positive thing about this Deep Green 1 Pack from Yolo Studio.
This "Deep Green 1 Pack (by Yolo Studio)" is unusable and should've been thrown into garbage can. Not only the two panels are unmatched shapes (or one panel is upside down) which make this mask very crooked, it is also all wrinkly. On top of that the zip lock bag holding it looks like a piece of beaten up trash which can't even zip at all.
I may give the 3 pack by e-Factory NY another try and hope they will match the 5 star experience of the "Hot Purple 3 pack by e-Factory NY".
