Extremely rare. Comes with Medusa box and cloth. These look a little like the mirrored wrap glasses worn by Data, Star Trek II.
These are partially mirrored front lenses.
These glasses have an almost unique wrap shaded visibility design. Oddly, this was seldom duplicated by other makers, or even continued by Versace himself.
I have seen only one other pair anywhere, and it was a butchered pair offered on Ebay for over $100.
