A heavy, compact slab serif with block-like proportions and a steady, mechanical rhythm. Strokes are thick and largely uniform, with broad, rectangular serifs that read as mostly unbracketed and square-ended. Curves are full and rounded inside the counters, creating a clear dark–light pattern despite the dense weight. The lowercase shows a straightforward, workmanlike structure with a single-storey “a” and “g” and a short, solid-shouldered “r,” while numerals are wide and sturdy with flat terminals and pronounced slabs.
Best suited for bold headlines, posters, storefront or wayfinding signage, and packaging where strong letterforms need to hold attention. It can also work for logo wordmarks and branded callouts that benefit from a sturdy, vintage-industrial feel.
The tone is assertive and practical, with a utilitarian, poster-ready presence. Its chunky slabs and compact shapes evoke vintage industrial printing and old-school signage, giving text a confident, no-nonsense voice.
The design appears aimed at delivering maximum impact through simple geometry, thick slabs, and compact spacing, prioritizing presence and durability over delicacy. It reads like a contemporary take on classic slab serif display faces intended for attention-grabbing typography.
The font produces strong horizontal emphasis from its slab serifs and broad caps, resulting in high visual impact in short lines. At larger sizes it reads crisp and architectural; in longer passages the dense color can feel heavy, suggesting selective use for emphasis rather than extended reading.
