ic! berlin sunglasses. BO-0036

Key Design Features
Brand: ic! Berlin (visible on the top left of the lens in the second photo). This is a premium German brand famous for using high-quality sheet stainless steel.

The Hinge System: If you look closely at the joints where the arms meet the front frame, you'll notice there are no screws . ic! berlin uses a patented interlocking hinge that allows the temples to snap off rather than break under pressure.

Frame Style: This is a double-bridge navigator shape. The matte brown finish paired with the brown lenses gives it a very classic, "earth-tone" aesthetic that works well for driving and outdoor activities.

Material: Likely 0.5mm stainless steel , making them incredibly lightweight and flexible compared to traditional acetate or heavy metal frames.
