A compact, heavy sans with tightly drawn proportions and a pronounced vertical rhythm. Strokes are consistently thick with minimal modulation, and many curves resolve into rounded-rectangle (superellipse-like) bowls that feel squared-off rather than purely circular. Counters are relatively small, terminals are blunt, and joins are sturdy, producing a dense, uniform texture in text. The lowercase shows a tall, sturdy structure with short extenders and simplified forms, while figures follow the same compact, weighty construction for strong alignment in headlines and numerals.
Best suited to large-scale applications where bold, condensed letterforms need to read quickly: headlines, posters, storefront or wayfinding-style signage, and impactful brand marks. It also works well for packaging and labels where space is limited but a strong typographic voice is desired.
The overall tone is forceful and utilitarian, with a modern, no-nonsense presence. Its compact width and dense blackness give it a poster and signage energy—confident, loud, and direct—while the softened corners keep it from feeling harsh or mechanical.
The design appears intended to deliver maximum impact in a compact footprint, pairing a heavy, uniform stroke with softened superellipse curves for a contemporary, industrial feel. It prioritizes solidity and consistency across characters to create a strong, uninterrupted typographic color in display settings.
In continuous text, the tight counters and heavy mass create strong emphasis but can reduce openness at smaller sizes. The rounded-rect geometry is especially evident in curved letters and numerals, giving the font a cohesive, engineered look across caps, lowercase, and digits.
