This Dog Bone face mask is made from premium materials: - There are two options to choose from: A durable two layered mask with a heavy duty lining to give you extra protection or the "New" light weight mask that has a nose bridge inserted. I use 100% soft Cotton fabric - Soft elastic ear loops. Not intended to treat, prevent or cure any diseases. These masks help reduce exposure to dust pollen and pet dander. They are a great barrier for general face protection.
