A sturdy slab serif with squared-off terminals and a distinctly blocky silhouette. Strokes are heavy and even, with minimal modulation, producing a dark, consistent color in text. Serifs are prominent and largely unbracketed, reinforcing a mechanical, built-from-parts feel. Counters are relatively compact and apertures tend toward closed, while curves (e.g., in C, S, 2, 3) stay firm and controlled rather than delicate. The overall rhythm is steady and uniform, supporting predictable spacing and a structured texture.
It performs well where a rugged, structured look is desired: code and terminal-style UI, labeling and wayfinding, packaging, and short-form typography like headlines or posters. Its steady rhythm and pronounced slabs also suit forms, tables, and any layout that benefits from a grid-like, utilitarian texture.
The tone reads utilitarian and industrial, with a clear nod to typewriter and early digital/printing aesthetics. It feels no-nonsense and workmanlike—confident, slightly austere, and suited to contexts that benefit from a tough, straightforward voice.
The design appears intended to deliver a robust, highly legible slab serif voice with a mechanical, typewriter-adjacent personality. It prioritizes consistency and firmness of shape over finesse, aiming for a dependable, industrial impression in both display and functional settings.
In running text, the heavy serifs and compact counters create strong presence and a slightly dense paragraph color. The numerals match the letters’ squared construction, keeping a consistent, engineered character across alphanumerics.
