||These cloths honestly do not work very well. I bought them thinking my mask would not fog much anymore, but no, they really only helped for an extra 30 minutes.
stops fog temporarily
Only get 3
reusable for like 2 times maybe 3
doesn't help against fog for very long
The guy below says they were the best ever made, when I bought anti fog for a car windshield and had WAY better results then these, and it was $5 cheaper....
