A rectilinear slab-serif with sturdy, even strokes and squared-off terminals, softened by subtly rounded outer corners. Curves are largely built from straight segments and squared bowls, giving counters a boxy, engineered feel. Serifs are heavy and flat, with compact joins that suggest slight ink-trap behavior at tight interior corners. Proportions lean tall with a high x-height, and the overall rhythm is tight and regular, emphasizing legibility through clear, modular shapes.

Best suited to display and short-to-medium text where strong structure and clear silhouettes matter—signage, posters, packaging, labels, and UI headings for tools or dashboards. It also works well for alphanumeric-heavy contexts like product codes or wayfinding, where its squared forms and heavy serifs keep characters distinct at a glance.

The tone is pragmatic and industrial, evoking labeling, machinery, and vintage utility printing. Its square geometry and firm slabs read confident and no-nonsense, with a mild retro-tech flavor that feels at home in functional signage and bold display settings.

Likely designed to provide a robust, legible slab-serif with a square, engineered construction—combining vintage industrial cues with consistent, modern-looking geometry for impactful, functional typography.

The lowercase shows strongly constructed, mostly monoline forms with squared apertures, while diagonals (such as in V/W/X/Y) keep a crisp, angular stance. Numerals match the same squared, mechanical logic, helping mixed alphanumeric strings feel cohesive and deliberate.
