This facemask with cupcakes and flowers has three layers. Both outer layers are made of 100% cotton. The middle filter layer, similar to those used in homes, filters out viruses, dust mites, pollen and other airborne particles. Our mask is the BEST mask because of the filtration element that has been added. The masks are soft, comfortable and have stretchy ear loops that allow for a perfect fit. Masks are washable and reusable, please enjoy! Keep safe in this era of Corona Virus / Covid 19.
