A compact, heavy sans with squared, superellipse-inspired contours and softly rounded corners. Stems are straight and uniform, with tight internal counters and narrow apertures that create a dense, poster-ready texture. Curves resolve into rounded-rectangle bowls (notably in O/C/G and 0/6/8/9), while terminals are predominantly flat and blunt, emphasizing a rigid, engineered feel. The lowercase is built from the same tall, vertical structure, with small counters and minimal calligraphic modulation; the overall rhythm is narrow and tightly packed, especially in all-caps settings.
Best suited for display use where maximum impact is needed—posters, headlines, branding marks, and bold packaging systems. It also works well for signage-style typography and short, emphatic statements, where its dense forms and compact rhythm can read as strong and intentional.
The tone is bold and commanding, evoking industrial signage and mid-century/Art Deco-inspired display lettering. Its compressed massing and squared curves read as mechanical and no-nonsense, with a distinctly retro, utilitarian confidence.
The letterforms appear designed to deliver high-impact messaging in a compact footprint, combining rigid vertical structure with softened superellipse rounding to keep the texture approachable rather than sharp. The emphasis on tight counters, flat terminals, and consistent block geometry suggests a deliberate nod to industrial and retro display traditions optimized for bold titles.
The design favors verticality and closed shapes: apertures and joints are kept tight, and many forms feel "stenciled" by their narrow interior spaces even though they remain solid. Numerals mirror the letterforms with rounded-rectangle geometry and strong, blocklike silhouettes, supporting consistent impact across headlines and numbering.
