This nylon satin face mask is three layers as recommended: nylon and 2 layers of cotton. It is machine washable and dryable. DO NOT BLEACH. If you need to iron it use a nylon setting then cover with a damp paper towel before ironing. The elastic is 10" long, soft and easy on the ears. I've left it exposed so you can adjust it if needed.
My masks are handmade in the US with love and concern for humanity.
Stay safe!
