I purchased these masks in a box of 100. They each come packed horizontally with the top and bottom part of the mask folded down, like pressed down into an elongated rectangle. The fit is close to the face, don’t fog my glasses, but the loops are a bit tight on my ears. My mother doesn’t like them, she prefers the vertical fold masks, also labeled as KN95 GB2626-2019, just like these. She said that unfolding them isn’t as easy as she’d like. My sister, however, prefers these and says they fit her face better than the vertical fold. I’ve never used these masks before, maybe takes some getting used to. It may be that they offer more protection being that the seal against the face is closer. My only complaint is that the product should use the description “Horizontal Fold”, or add a suffix to the part number in case you’re looking for the other type.
