The P63 BZ-HB is KUBORAUM's P-Series in rimless hexagonal architecture. Each brown lens is cut to a hexagonal shape and held in place at the bridge and temple by bronze-toned metal hardware - no frame surrounds the lens itself, only the metal connectors that anchor it. Small round black bead accents sit at each temple hinge, picking up the chromatic register of the brown.

The temple lengths read as Havana brown layered with Black Shine, attached to the lens by visible bronze metal arms. Lens width fifty-six millimetres, bridge seventeen, temples one hundred and forty-five. This is KUBORAUM at minimum frame mass - the lens shape and the metal hardware do all the work.
