Two layers of cotton material styled like a typical mask you would get at a doctor's office. Elastic straps (1/4 inch wide) go over ears. Bias tape channel on inside upper edge may be used for nose wire, small paper clip, pipe cleaner, twist tie, etc., if desired, but it is not necessary. Washable. Remove wires before washing. Safety Note: Bend ends of wire in a circle or wrap with tape to avoid sharp ends. Use at your own risk. Note that our reusable face masks are not medical devices or personal protective equipment (PPE).
