A tall, condensed sans with extremely thin, monoline strokes and generous vertical proportions. Curves are built from softly squared, superellipse-like rounds that keep counters narrow and controlled, while straight stems remain rigid and clean. Terminals are crisp and unadorned, with occasional subtle hooks or tapered joins in letters like J, y, and a, adding a delicate calligraphic echo without breaking the overall geometric discipline. Spacing appears restrained, producing a tight, vertical rhythm that reads like a continuous series of slender columns.
Best suited to large sizes where the hairline strokes and narrow counters have room to breathe—headlines, brand marks, fashion/editorial titling, packaging, and minimalist poster work. It can also work for short subheads or labels when given ample size and contrast against the background.
The overall tone is quiet and sophisticated, leaning toward fashion and editorial minimalism. Its attenuated forms and glassy line weight feel modern and upscale, with a slightly art-deco-inspired poise driven by height and symmetry rather than ornament.
Designed to deliver an ultra-sleek, space-saving display voice: condensed proportions for strong vertical presence, superelliptical roundness for a modern geometric flavor, and hairline strokes for a high-end, understated finish.
Round letters such as O, Q, and 0 share a consistent rounded-rectangle skeleton, helping the set feel cohesive. The numeral set follows the same narrow, linear logic, with simple construction and minimal modulation, reinforcing a clean display personality.
