These are made of both 100% cotton and a cotton blend and there is a slot to insert a HEPA filter. Sewn in Hawthorne, by an invaluable member of our team. When you buy from us, you are not just buying from two people, you are buying from a community.
PLEASE be patient with our shipping. We are getting our items out as fast as possible but Covid19 is making turnaround time a lot slower than usual. We appreciate your support of our small business!!! GRACIAS.
