THESE ARE DIGITAL FILES ONLY !!! You are not buying a physical helmet or costume.
This is a complete 3D file set in *.STL stereolithography format to pint the parts to construct the helmet, Control box, handheld Reader Screen, and the Lower spine connector for the Lensor character in the movie Chronicles of Riddick.
YOU print the parts from these files, finish and assemble them to your cosplay or movie replica. These are only digital files you are buying.
I expect to have an instructables created soon from which I will guide you how to build it but it is fairly straight forward.
Please contact me with any questions you might have.
