At Kosby, innovation and quality are always paramount! The result of years of research and development are the two patents on the designs. One covers the complex, extra-flat flex hinge, and the other patent covers the elimination of the box screw. A technical design that simplifies the installation of inline frames.
Design, Materials and Finish
Kosby frames are lightweight, timeless, and stylishly designed. Kosby offers a broad, technical collection with a high-quality, designer look. The frames are crafted from high-quality stainless steel and acetate. The unique, soft, and understated color is the result of a high-quality lacquer treatment, applied by the finest companies in the French Jura region.
