Specifically made to fit the Impact Props Halo 4/5 Master Chief helmet (sold separately)
Vacuum formed PETG plastic
Dyed amber and mirror polished
There is a protective shield installed on the back surface of the visor to protect the one sided chrome coating. This is a fan made replica and is intended for collecting, displaying, and costuming, not protection. There is no guarantee this will fit other Master Chief helmets on the market.
To install, simply hot glue the visor into place. There are a number of other installation methods that are outlined in tutorials on Youtube.
