A sturdy slab serif with square, flat-ended terminals and a compact, blocky construction. Strokes remain largely even throughout, with broad, rectangular serifs and firm joins that create a steady, mechanical rhythm. Counters are generous for the weight, and curves on forms like C, G, O, and S are tightened into squarish arcs, keeping the overall silhouette crisp. The lowercase follows the same straightforward geometry, with a single-storey a and g and a clear, workmanlike presence across letters and figures.
It works well where strict alignment and unmistakable character shapes matter, such as coding environments, terminals, tables, and technical documentation. The strong slabs and dense color also suit labeling, signage, packaging callouts, and compact headlines that need a rugged, authoritative feel.
The face conveys a practical, no-nonsense tone with strong typewriter and shop-floor associations. Its rigid geometry and emphatic slabs feel assertive and dependable, leaning toward a vintage editorial or institutional mood rather than a delicate or expressive one.
The design appears aimed at delivering a highly legible, monoline slab serif with a disciplined, typewriter-inspired voice. Its square terminals and firm serifs prioritize clarity, repeatability, and a consistent typographic texture across mixed-case text and numerals.
Letterforms show consistent spacing discipline and uniform proportions that support a measured texture in paragraphs. Numerals are heavy and clear, and punctuation adopts the same squared-off, solid style, reinforcing a cohesive, engineered look.
