Not only the length, but also the color of the temples can be easily changed in this way. Each color and finish is available in 130mm and 140mm for re-ordering.
The only difference to the pre-assembled parts is the neutral laser-marking on the underside of the replacement temple pair. Instead of the name of the respective model you can read the abbreviation CSTMZD4U here: Customized For You. On the right temple, following the CE-symbol, the titanium color replaces the polyamide color.
