All of our mucous membranes are susceptible to COVID-19, including our eyes. Unlike a face mask, these face shields help protect your eyes, nose, and mouth. It is wise to take precautions and wear a face shield while in public. Additionally, if you wear a face shield and face mask together, you significantly reduce the risk of catching the Coronavirus. These face shields are reusable and easy to clean, so you do not need to stockpile these. For that exact reason, these are sold in a quantity of 12 face shields per box. Face shields are great for both professional and personal use.
