This is a non-medical protective face mask. The surgical style face mask expands to ensure both your nose and mouth are completely covered. Each mask is approximately 9" wide and 6" tall when fully expanded. You can choose between fabric ties or elastic loops for best fit/comfort. Fabric ties: tie the top two ties around the back of the head over the ears to ensure it doesn’t slip down. Secure the bottom two ties around the back of the head where it meets your neck. The ties have been stitched to prevent fraying, but if you get loose strands from use, you can cut them off or leave them alone- it will not continue to fray. Elastic loops: place one elastic loop behind one ear, pull the mask across your face to cover your nose/mouth, and pull the second loop behind your other ear.
