These are custom colored face mask clips which you can now add to give your mini helmet a custom look. The clips can add a bit of nostalgia by looking like the 70's or 80's colored facemask clips. Or if you'd like to add them to look like the Shock Blockers which current players wear on the side mounted clips. They are easy to put on with only a screwdriver. Each set comes with four custom clips and four mounting screws.
