The OCCHIO edit
K5 Black Matt combines a cat-eye shape with matte black. Look first at the outer corners: they create a different direction from the rectangular Q8. View both frames from the front and compare how the upper line relates to the eyebrows.

Find your fit
Look for the three numbers inside the temple of your current glasses: lens width, bridge width and temple length. Compare them with these measurements. The frame shape and nose fit matter as much as the numbers.

About this frame
The upper edge rises towards the temples, while matte black brings the outline into focus. Kuboraum K5 Black Matt is an acetate optical frame with a cat-eye shape, a defined front and temples that continue its line.
This version lets you study the K5 shape: muted reflections, visible depth and a distinct outline on the face. Designed in Berlin and handmade in Italy.

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.
