"The Prodigy Reusable Face Mask is here to help keep you safe while providing long term comfort and a fashionable look. The masks are made of a lightweight and breathable Polyester/Spandex blend for comfort, and the shape allows them to not constantly rub your face. There are several different colors and patterns available and are one size fits all with the adjustable elastic straps. Each mask comes with three PM2.5 filters which can be inserted into the mask for an extra layer of protection from external elements like dust, debris, and pollution. The Prodigy Face Mask is washable and reusable to help keep you protected for outdoor travel, the grocery store, airports, and any other public places. The Prodigy Reusable Face Mask is not a medical-grade mask and does not prevent the transmission of diseases."
