IC! Berlin revolutionized eyewear with their very first frame – a screwless sheetmetalframe. How does screwless eyewear work? With an ingenious removable clip that holds the frame and temple together at the hinge. Every ic! berlin frame features this remarkable hinge, meaning every frame can be broken down into its individual parts and reassembled quickly, easily, and without any extra tools. No screws. No glues. No welds. No witchcraft. Pure design.
