A single tinted shield with gear-like mechanical metalwork at the temple junctions - the E15 BB pairs a continuous lens against intricate hardware. The E15 BB is KUBORAUM's E-Mask in single-shield format - a one-piece Carl Zeiss-style nylon lens that crosses the entire face, anchored at each side to articulated metal temple junctions with visible gear-like coil construction. Electric green tint runs across the lens, which reads warmer at the centre and slightly more saturated at the edges where the curvature catches more light. The lens spans one hundred and forty-four millimetres side to side - this is mask architecture, not regular sunglasses. There is no traditional bridge; the shield rests against the upper nose with a small black acetate inner contact. Ruthenium-finished metal hardware at the temple ends carries the mechanical detail. Acetate at the very tips of the temples for ear contact.
