These are easy to use and provide a better fit.
I found that I had to lay the mask as flat as I could and stick on the nose bridge and then put a heavy book or two on top and leave it for a while. By doing this the bridge stay firmly affixed to the mask.
The nose bridge can be a perfect fit for whatever size bridge you have. I have a very narrow bridge and am able to pinch this nose bridge to fit without breakage. Very flexible.
good. Mask never slips off my nose
I unfortunately never got my item. I reached out to customer service to inform them I had never been updated about shipping info and I was assured it was shipped, and was told that I had to be more understanding that the post office was very busy and not everything get scanned.
