A mask you wear in Asia if you have a cough or cold

Pick masks up free from some clinics and hospitals. Such a good idea. You don't want to cough over other sick people nor sneeze over doctors.

I put the mask down flat to take a photo. Interesting that it is blue. Also when you see it laid out flat, you can appreciate the construction. It is constructed with folds so that it expands over your nose.
