A heavy, compact display sans built from squared-off, rounded-rectangle forms and broad vertical stems. Corners are consistently softened, producing a superelliptical geometry, while counters are tight and often rectangular, giving letters a dense, engineered texture. Contrast is expressed through deep internal cuts and sharp notches rather than stroke modulation, with several glyphs showing ink-trap-like scoops at joins and terminals. The lowercase is tall and sturdy with short extenders, and the overall rhythm alternates between wide, boxy shapes and narrower, more compressed forms, creating a distinctly modular line color.
Best suited to large-size applications where its carved details and tight counters can be appreciated—posters, headlines, branding wordmarks, packaging, and bold wayfinding or signage. It can also work for short emphatic UI labels or badges, but is less appropriate for long-form reading due to its dense interior spaces and strong display character.
The font reads as bold, tough, and slightly playful—like stamped lettering or heavy industrial signage with a retro-futurist edge. Its squared curves and carved-in details give it a mechanical confidence, while the rounded corners keep it friendly rather than harsh.
The letterforms suggest an intention to create a compact, high-impact display sans that feels engineered and modular, using rounded-rectangle construction and pronounced interior notches to maintain clarity and personality at large sizes.
The design leans on distinctive cutouts and notched terminals (notably in characters like S, J, Q, and several numerals), which become a key identifying motif at text sizes. Spacing and shapes appear optimized for impact rather than neutrality, and the dense counters can close up visually when set too small or tightly tracked.
