The frame is made from a black sheet while the sides are made from red sheet.

These are quality frames machined out of high density sheets of acetate. These looks similar to cheaper molded plastic frames, but are tougher than injection molded plastic frames. These are durable like metal frames but comfortable in touch like cheaper plastic frames. They are relatively (little) heavier than ordinary plastic frames.

These are made from hypoallergenic materials, meaning they contain few allergy-producing substances.
