Combo Frames were very popular in the 70's and 80's. They got their name because they were made from a combination of metal and plastic. They have made a comeback to some degree with the repros, but not as much as some of the other styles. Como Frames were usually bought because of the lighter weight. Many combo frames were made from composite materials for the frame, and thin lightweight wire for the stems. Our entire inventory is unused vintage. Most of them still have the demo lenses installed. Check out our selections and see if there is something there for you.
