These are fashion face covers, NOT medical grade masks. They are 100% polyester, washable with non-chlorine bleach and dryer safe. The designs will not chip or peel off. This design will sure put a smile on somebody else’s face…and yet super soft to wear. Given the nature of this product, ALL SALES ARE FINAL, no refunds or exchanges. One size fits most. They are designed to remind you not to touch your mouth or nose.
