A heavy, slab-serif design with strong vertical emphasis and flat, squared terminals. Strokes are predominantly uniform and dense, with compact counters and assertive serifs that read as solid blocks rather than delicate brackets. Curves (as in C, O, S) are broad and rounded but finish with firm, squared joins that keep the overall texture crisp and architectural. The lowercase is compact and workmanlike, with single-storey forms visible in a and g, and a sturdy, squared-shoulder rhythm across n, m, and h. Numerals are large and sturdy, with simple, emphatic silhouettes that hold weight well in display sizes.
Well-suited for headlines, subheads, and short-to-medium editorial callouts where a solid, authoritative voice is desired. It can also work effectively for branding, packaging, and signage that benefits from sturdy letterforms and high visual impact.
The overall tone feels assertive and no-nonsense, combining a traditional, print-oriented seriousness with an industrial, poster-ready punch. Its dense color and squared detailing convey reliability and authority, leaning more toward practical editorial impact than delicate refinement.
The design appears intended to deliver a forceful slab-serif voice with squared finishing and a dense typographic color, optimized for attention-grabbing display and editorial emphasis. It prioritizes firmness, stability, and clear silhouettes over lightness or calligraphic nuance.
In text, the font maintains a strong, even typographic color with minimal stroke modulation, producing a dark, stable line that favors presence over airiness. Wide, block-like serifs and tight interior spaces help letterforms stay distinct at larger sizes, while smaller sizes may appear compact due to the heavy weight and small counters.
