A tall, condensed sans with a monoline feel and gently rounded terminals. Curves are drawn with a soft, superellipse-like geometry, giving bowls and rounds a slightly squared-yet-rounded character. Strokes stay even, with subtle narrowing at joins and compact apertures that keep the silhouette crisp. Uppercase forms are narrow and vertical, while lowercase maintains a straightforward construction with simple ascenders/descenders and minimal detailing, creating a steady, rhythmic texture in text.
Best suited to headlines and compact display settings where narrow width is an advantage—posters, book covers, packaging, and editorial titling. It can also work for short bursts of text (captions, pull quotes) when a distinctive, space-saving voice is desired.
The overall tone feels retro and lightly whimsical—like mid-century display lettering translated into a clean, consistent text face. Its narrow, upright stance reads energetic and tidy, while the softened corners keep it friendly rather than austere. The result is distinctive without relying on heavy ornamentation.
The design appears intended to deliver a space-efficient, characterful sans that blends clean monoline construction with rounded, superellipse-inspired curves. It prioritizes a recognizable silhouette and vertical rhythm for display use while staying simple enough to remain legible in short text runs.
The font’s condensed proportions create strong vertical emphasis, and the rounded-rectangle curvature shows most clearly in O/C-style rounds and in the softened ends of vertical strokes. Numerals are similarly narrow and upright, matching the alphabet’s compact rhythm for cohesive mixed typography.
