Handmade in Berlin, the Titan 3D sunglasses, courtesy of Germany’s Onono brand, are crafted from a single sheet of titanium, leaving them entirely free of screws and creases. That, however, doesn’t mean they will fall apart after the first wear. Their design employs the use of a unique hinge system with a detachable clip – an innovation for which a patent is said to be pending. With their futuristic appearance, these shades are not only stylish, but also represent an industry first for crafted sunglasses. Their titanium frames are lightweight – only nine grams – and are also said to be wholly corrosion-resistant.
