A compact, monoline slab serif with octagonal, flat-ended terminals and blocky geometry throughout. Strokes maintain an even weight with minimal contrast, and corners resolve into squared shoulders and chamfer-like joins that give letters a constructed, stamped feel. Serifs are short and heavy, often reading as rectangular tabs rather than tapered forms, and the overall rhythm is tight with relatively narrow proportions and firm vertical emphasis. Numerals follow the same squared, mechanical logic, with the 0 rendered as a boxed oval and many forms built from straight segments and right angles.
Well-suited for headlines, posters, and packaging that benefit from a tough, industrial voice. It also works nicely for labels, signage, and display copy where its blocky slabs and mechanical construction reinforce a technical or utilitarian theme.
The font conveys a rugged, workmanlike tone—mechanical and slightly old-fashioned, like lettering from industrial labels, stenciled equipment, or early typewriter and teleprinter output. Its hard corners and dense color feel practical and no-nonsense, with a subtle retro grit that suggests production, tools, and technical documentation rather than elegance.
The design appears intended to translate slab-serif structure into a distinctly square, engineered language: sturdy, compact, and optimized for bold presence in display settings. Its consistent, tab-like terminals and constructed outlines suggest an aim for a stamped or machined aesthetic with strong visual uniformity across letters and numerals.
In text, the squared detailing and tight spacing create a dark, emphatic texture that holds together well in short bursts. The geometric shaping can reduce differentiation between similar forms at smaller sizes, so it tends to read best when given enough size or generous leading.
