This kid's mask has a fun, playful look, they are sure to love. The pleated double layer fabric provides extra protection and full coverage over the top of the nose and bottom of the chin. The elastic straps have rubber adjusters that slide in place to keep the mask securely in place. One size fits most. These masks are for general non-medical purposes only.
