Question 1

why can't these be washed?

Accepted Answer

Perhaps they have paper or other materials that would be damaged by water. Sounds like you want a cloth mask. Recent research indicates that masks that are made of layers of different materials work better than simple cotton. Forbes has an article about this.

BTW, I live in a rural, low-risk area, and reuse these many times. I just store them in a baggie to keep them clean.

Question 2

Is this 5 cellophane bags with 10 masks in each for a total of 50 per box?

Accepted Answer

Yes that is exactly how it's packaged. Purchased just as fall-backs to my 3 cotton reusable ones
