This is one of my favorite Liberty of London fabrics! This is not a medical mask. It does meet the CDC guidelines for fabric face coverings. It is one layer of silk/cotton (30/70), one layer of non woven innerfaced and one layer on finely woven cotton. This mask has a little rubber things that allow you to adjust the elastic. If you prefer straps, just let me know.
Hand wash with mild soap. If it falls in the washer or dryer it will be ok, just press it as needed. A cycle through a hot dryer may be helpful according to the CDC. This will not hurt the mask, just may need to be pressed. Please let me know if you have any problems.
