Porsche Design Carrera 5621 unisex sunglasses with exchangeable brown and blue-grey lenses, enclosed within the original case. The glasses are in good condition with only those signs of wear that can be expected due to normal use. The glasses can be stored in the original Porsche Design Carrera case. In the centre of the glasses there is a hinged handle to attach and detach them as you wish. The Carrera Porsche sunglasses were introduced in the 1980s and are now worn both by men and women. The lenses are made of optyl (lighter than glass and hence better suited for a larger frame). One temple reads 'Made in Austria 5621', the other 'Carrera Porsche Design', and the ear pad states the patent number 'U S PAT 4 . 176-921'.
