Custom Luxury face masks are available as a pack of four. Made with quilted Jersey for a heavyweight breathable jersey ply with a wadding layer featuring quilted diamonds. Machine washable and reusable, tumble dry safe. These are not medical grade masks and should not be used as such. Rather these masks are meant to provide some level of protection for the transmission of water droplets for non-medical personnel as to not take medical grade supplies from doctors on the front lines. In the medical field, we have been advised that this style mask has been used as a protective cover placed over a medical grade mask to prolong the usable life of the medical grade mask.
