I AM SELLING UNFINISHED RAW CASTINGS.

This is a fan made, life size, Halo 4 Marine helmet, based off Halo 4 Sparan opps. This listing is for a RAW plastic casting & is not a finished painted helmet.

This was made to fi a 23" head and can accommodate slightly smaller larger & smaller but it will require padding for a proper fit.
The helmets in the pictures are a mixture of finished casting as well as unfinished rawcastings. The cast are made from my original sculpture & pics of the build can be seen on face book at stony props.

If requested I can add a custom fiinsh yours according to your specs for an additional fee.
