A slender monoline sans with tall proportions and tight letterfit. Strokes are consistently thin with smooth, rounded-rectangle curves in bowls and counters, giving O/Q/0 and related forms an elongated, superellipse-like feel. Terminals are clean and mostly straight-cut, and the overall construction is simple and geometric with minimal detailing. Numerals and capitals maintain the same narrow, vertical rhythm, producing an even texture at display sizes.
Best suited for headlines, posters, logotypes, and short editorial passages where a tall, minimal rhythm is desired. It pairs well with spacious layouts and can add a refined, contemporary flavor to branding and packaging when used at larger sizes.
The font conveys a quiet, minimal elegance—precise and contemporary rather than expressive. Its light presence and compressed stance feel fashion-forward and architectural, lending a refined, understated tone.
The design appears intended to deliver a sleek, space-saving display voice with a clean geometric skeleton and softly squared rounds. It prioritizes vertical elegance and a consistent, pared-back stroke system for modern, high-clarity typographic compositions.
Curved letters (C, G, S, O, Q) read as softly squared ovals rather than perfect circles, while straight-sided forms (H, N, M) emphasize verticality. The thin joins and narrow counters suggest it will look best with generous tracking and sufficient size, where its delicate lines can remain crisp.
