Material combinations are being offered more frequently than in the past, in addition to new natural materials and 3D-printed eyewear. Kuboraum, the Berlin-based eyewear brand, won the special prize of the jury at this year's Silmo awards in Paris for its Mask E3 sunglasses, made of 60 percent acetate and 40 percent stainless steel. The model was presented at the 2016 edition of Silmo for the first time.
