Softly translucent, matte surface, unique color palette. The frame variants of Gira Event Opak are made from opaque plastic, a slightly light-transmitting material. Depending on the light incidence, the colors appear to change from lighter to darker, and the curved shape of the frames enhances this effect. Gira Event Opak is available in the colors amber, mint, blue, red, white, orange, and dark brown.
