A heavy, block-built sans with rounded-rectangle (superellipse) foundations and tightly controlled internal spaces. Strokes are thick and consistent, with squared terminals softened by generous corner rounding. Many letters show small vertical interior slits and notch-like cut-ins that create sharp light traps and add texture, especially in bowls and joins. Proportions run wide and stable, with compact counters and a sturdy baseline presence that keeps forms legible at display sizes.
Best suited for large-scale applications such as posters, headlines, logotypes, athletic or team identities, and punchy packaging. It can also work for short UI or product labels when set large enough to preserve the tight counters and distinctive internal cuts.
The overall tone is assertive and utilitarian, evoking industrial labeling, athletic branding, and techno-era display typography. Its dense massing and engineered details feel bold, confident, and a little aggressive, lending a rugged, stamped sensibility to headlines.
The font appears designed to maximize impact through dense black shapes and a consistent superellipse geometry, while adding character via slit-like counters and notch details. The aim is a distinctive, robust display voice that feels engineered rather than calligraphic.
The design relies on repetition of similar rounded-rectangular shapes across both uppercase and lowercase, producing a strong rhythm and a cohesive, modular feel. In smaller text, the narrow internal openings and decorative notches can become dominant, so it reads best when given room and size.
