Those people who really need it and there are ony few supplies available in thier country.

The price is so expensive because we are now in the need with that medic supply like mask. In my country even alcohol is out of supply .

If you can buy mask in your country there is no need to buy expensive one. If you can makke your own mask this is much better than buying , you will not need any mask if you just stay at your home and dont go out .
