A highly condensed monoline sans with tall proportions and generous vertical emphasis. Strokes are extremely thin and consistent, with rounded-rectangle (superelliptic) bowls and softly rounded corners that keep curves clean and controlled. Terminals are mostly straight and understated, counters are narrow but open, and the overall rhythm is evenly spaced with a crisp, engineered simplicity. Numerals and lowercase follow the same elongated, streamlined construction, maintaining a consistent, slender texture across text.
Best suited to display use such as headlines, fashion or culture editorial titling, posters, and brand marks where its tall, delicate silhouette can stand out. It can work for short subheads or UI labels when sizes are sufficient and contrast is high, but its fine strokes and condensed forms are most effective in larger applications.
The font conveys a quiet, refined modernism—cool, delicate, and intentionally restrained. Its thin lines and lofty proportions suggest sophistication and precision, with a slightly fashion/editorial tone that feels light on the page.
The design appears intended to deliver a sleek, space-efficient display voice built on geometric, rounded-rectangle forms and an ultra-clean monoline skeleton. The emphasis is on elegance and modern clarity rather than warmth or typographic heft.
The narrow set width and hairline strokes create a distinctive vertical texture that reads best when given space. The rounded-rectangle construction is especially apparent in letters like C, O, Q, and the lowercase bowls, reinforcing a cohesive geometric theme.
