Complete your Master Chief costume with this Halo mask! The licensed 1/2 mask is made of plastic and secures to your face with an elastic velcro band behind your head. The green mask features black accents and "scuff marks" for an authentic, worn appearance. The gold visor has a metallic strip over the eyes so that you can see out, but no one can see in. (Please note: the metallic visor is smaller than what is pictured). There are slits near the nose and mouth for easy breathing. Transform into Master Chief with this Halo mask!
