All frames are 100% hand-drawn style and original. All acetates are original cellulose (plant) based with original long-diamond-tooled core wires and original arrow-shaped hinge design and constructed using an old school star-nut configuration to adjust and hold hinge tension, making it harder to loosen. The beauty marks accenting the front connections and side temple appear striated and are finished in antique plating then hand polished to leave a hairline finish.
