This mask by #LuminitA is no different than putting a lace piece of cloth over your mouth. There is NO WAY it will block dust from getting into your nose and mouth. . I wouldn't give $.10 USD For this . I have better scarves I can use it hat I paid a lot less. If I could give this zero stars I would. I already requested a refund. To get 2 pieces for $29.99 is price gauging at its finest. Not even worth $.10 each. Save your money and buy something worth it. Th ou s one definitely doesn't do it.
