One design is small butterfly shape. Another is modern slightly oversized feminine shape. The third draws its inspiration from the classic hexagon shape. The HEXA concept is a bold and expressive take on our essential collection – showing the wide variety of possibilities within the Prodesign universe. Across its different variations HEXA is characterized by a consistently elegant recognizable hexagonal shape – demonstrated in the stainless steel temples, the front rivets and even in the acetate end tips. We’ve ensured a perfect tumbling & polishing of the acetate, so it compliments the sharp edges of the hexagon shape.
