About this frame
The Kuboraum K5 ML takes the K5’s cat-eye design toward lighter tones. In photos, the irregular surface of the front gives its outline more movement, while in profile you can see the bold line of the temples.
Compare it with Black Matt and Ossidiana to see how much a finish can change the presence of the same frame. The K5 ML is made of acetate, designed in Berlin and handcrafted in Italy.

Explore all Kuboraum glasses, optical frames and sunglasses.
KUBORAUM calls its frames “masks”. The idea is that eyewear can change how we see ourselves and how we present ourselves to others: an object through which to play, recognise ourselves and express different aspects of our personality.
The name evokes a cubic room, a personal space in which to feel at ease and free to be ourselves. This image shapes the brand’s approach, treating the frame as a place to inhabit, close to the face and to individual identity.
