This is the largest black strand I found in the white blue face masks. This is a brand new face mask. I can find about 4 to 10 of these black strands in all of the white blue face masks I have. I was breathing hot and cold air onto it and as you can see it reacted and popped out at one point so I had to readjust the microscope. This video was done in 120x magnification. Just think, when you are wearing a mask, you are breathing in, these black strands will most likely go into your nose or mouth into your system. Most of the black strands I found were woven into the mask and did not pop out like this one.

Another what seems to be a black plastic strand that reacts to heat and cold. Video is in 120x magnification. I found these black strands in all my paper white blue masks. I can find about 4 to 10 of them in each mask. When you are wearing a mask, you are breathing in and these black strands could go up your nose or into your mouth. These black strands cannot be seen with the naked eye.
