Genuine tempered glass (not a translite). This is a CPR custom-mirrored reproduction, with silkscreened mirror inks. Polished corners and edges, ready for new trim and lift bar. Gorgeous replacement, finally get rid of that old chipped, crackled, or shedding original backglass. A fantastic upgrade to pimp up your Taxi machine. Especially the rear view mirror, which now will be real mirror (not a plastic faux silver taped to the back).
