These are brand-new Nintendo NES-004 controller shell replacements. They are designed to be just like the original. They are manufactured here in the United States of America and are available in a variety of colors. They come with the appropriate screws. If you need the inlays on the front of the controller, I also have these for sale.
I own the injection mold for these and so I can make them in different colors beyond the ones listed for additional fees.
