A spare, monolinear slab serif with a distinctly rectilinear construction. Strokes keep an even weight throughout, while terminals resolve into small, square slab-like serifs that read as crisp caps rather than flared endings. Many bowls and curves are squared off into rounded-rectangle forms (notably in C, D, O, and 0), giving the design a geometric, engineered feel. Proportions are compact and vertically oriented, with tall ascenders/descenders and a measured, regular rhythm across text.
Well suited to display typography where a precise, engineered voice is desired—headlines, poster titles, tech-forward branding, and packaging. It can also work for short editorial callouts or captions when set at comfortable sizes, benefiting from generous tracking and clean backgrounds.
The overall tone is clean, technical, and slightly futuristic, evoking drafting, instrumentation, and early digital/industrial signage. Its thin, precise lines and boxy curves feel deliberate and controlled rather than expressive or calligraphic.
The design appears intended to merge slab-serif structure with a geometric, squared-off skeleton, prioritizing crisp terminals and an industrial, constructed silhouette. It aims for a distinctive display presence through rectilinear curves and consistent, measured stroke behavior rather than contrast or ornament.
Counters tend to be narrow and rectangular, and joins are handled with sharp interior angles, reinforcing the constructed look. In text, the font maintains clarity through consistent stroke logic and firm terminals, though the light build suggests it will read best when given adequate size and spacing.
