Plastic frames are as popular today as they were when these frames were produced. The difference is simply the price. You can easily spend $200-$300 at the retail stores for product that isn't as robust or stylish. In additon so many of the vintage styles have come back and reproductions are being made by many of the manufactures. They look the same but the price is always higher and the quality is usually lower. Take advantage of these unused vintage frames that have been uncovered in a warehouse find. All listings are authentic vintage and unused. They have never been worn or had perscription lenses in them. Most still have the original demo lenses for faster fit to your perscription.
