A monoline, condensed sans with tall proportions and rounded-rectangle (superellipse-like) bowls. Strokes are extremely thin and even, with a consistent vertical emphasis and carefully controlled curves that terminate in softly rounded ends. Counters are narrow and elongated, giving letters a slim, columnar rhythm; joins and shoulders stay restrained and smooth rather than calligraphic. Numerals follow the same slender, rounded geometry, with simple, open forms and minimal stroke modulation.
Best suited to large-size display settings such as headlines, posters, logotypes, and premium packaging where its thin strokes and elegant narrow rhythm can be appreciated. It also works for short editorial titling and UI moments that call for a delicate, high-end accent, but it is less appropriate for dense body text or small sizes due to its very light construction.
The overall tone is quiet and refined, with an airy, modern feel. Its ultra-thin construction and elongated shapes suggest precision and sophistication, leaning toward a sleek, architectural or editorial mood rather than warmth or playfulness.
The design appears intended to deliver a sleek, contemporary display voice by combining ultra-thin monoline strokes with superellipse-based rounding and condensed proportions. The goal seems to be a distinctive, space-efficient headline style that feels refined and precise while maintaining a clean sans structure.
Round letters (like O/C/G) read as tall capsules, while diagonals (V/W/X/Y) are drawn with long, sharp lines that heighten the vertical, high-fashion silhouette. The design’s light stroke and tight internal space make spacing and size choices especially important for comfortable reading.
