The M3 X is made of TMi plastic, a material especially developed for this series of glasses, and weighs only 8.5 grams at a material thickness of 7 mm. The striking depth of material lends the glasses an impression of spatial depth, while the translucent colours of the front convey lightness. Clear, slightly curved lines complement the overall appearance. A click system allows the lenses to be easily inserted into the frame. The handmade model is constructed without screws and thus requires minimum maintenance.
