The Personal Face Shield is a clear plastic visor with two heavy duty grippers that attaches to the rims of most baseball style caps and hats (not included.) It offers personal protection from sneezes, coughs and other potentially harmful interactions with the public. The visor measures 13.5″ wide by 9″ high and can be easily wiped clean and sterilized. The shield is made in the U.S.A., ships flat and is virtually shatterproof.
