New and unworn from deadstock in mint condition Measurements cal 60-18 Overall 13.7 cm Lenses width 6 cm height 4.4 cm Temples 13.5cm ** I wrote Audi Quattro because the writing on the temples is exactly identical to that of the Audi automobile; and it's not a coincidence given also where they are produced I guess :)
