JINS Konstantin Grcic TYPE PRETZEL URF-18S-349 MADE IN CHINA Round clear Round clear Non-prescription Blue light cut (Lenses can be replaced at any JINS store for a fee.) Konstantin Grcic is a product designer based in Germany and active worldwide. He has created simple, high-quality products while stripping away unnecessary elements and maintaining significance. Eyewear design is his first endeavor. "Anonymous, basic, and at the same time, a form that holds a strong statement." Through repeated research and deepening his understanding of glasses, he focused on the round shape, which is the origin of glasses and has been chosen by many famous people throughout history as an item to highlight their individuality. By focusing on the round shape as a base and adding a modern interpretation, the design has become one with diverse styles.
