Jewelry, Eyewear and Watch Design JAM Vision Track3 Sustainable Innovative Eyewear by Brusset Sébastien The Track3 eyewear has been designed to be as eco responsible as possible, either in the production method, or in its lifecycle. Fronts and tips are made in PA11 3D printed, to limit the waste to almost nothing. Temples and bridge are made in 100% recycled stainless steel, laser cut. Everything is made on demand to avoid stock and wastage. Then all the parts are mechanically assembled without soldering or even glue. So every single parts could be repaired. Thanks to the patented magnetic hinge, no risk to loose any screw, and friction performance is lifetime guaranteed (tested 100.000 times!).
