When pre-ordering this item the delivery consisted of a mask with a nice metal cap and a nicely shaped "dipped" cut-out at the bridge of the nose which allows the mask to provide a comfortable and good seal. However, the last order was of a poor quality construction that doesn't seal well and doesn't have a "drooping" nose cutout. The ear loops come loose easily (that's the case with most kn95 masks) but I fix that by sewing a simple seam around the mask, which is a bit awkward as it takes about 30 seconds. But it allows me to pull the ear loops on the ponytail at the back of my head and actually fit the edges of the mask snugly to my face. Wearing a mask with loops around the ears simply creates a gap, and wearing a mask like this does not filter the air, it is just a symbolic gesture.
