Our designer non-medical face masks are made from 2 layers of high quality cotton from the finest European mills. They are made by our skilled seamstresses right here in Texas, USA. To ensure a great fit, they have pleated sides and are gathered top and bottom with stretch binding, which extends into long ties to shorten as needed. They also have a filter pocket to add your own filter if you wish. They come to you pre-washed and are machine washable. For health concerns all masks are not returnable.
