A heavy, squared sans built from rounded-rectangle geometry, with broad stems, soft corners, and largely monoline construction. Curves resolve into superelliptical bowls and counters, giving letters like O, C, and G a squarish roundness rather than true circular forms. Terminals are blunt and flat, apertures are tight, and interior counters are compact, producing a dense, high-impact color on the page. The lowercase follows the same blocky logic with sturdy shoulders and short joins, while figures are similarly squarish and robust for consistent texture in mixed text.
Well suited for short, attention-grabbing typography such as headlines, posters, labels, and display branding where a compact, powerful texture is desirable. It also works effectively in signage and wayfinding-style applications, especially when set with generous spacing and ample size.
The overall tone is forceful and utilitarian, with a confident, engineered feel. Its rounded-square forms add a friendly softness to an otherwise tough, industrial voice, suggesting contemporary sport, tech hardware, and bold signage.
The design appears intended to deliver maximum impact with a cohesive rounded-square system, balancing toughness with approachability. By emphasizing blunt terminals, compact counters, and superelliptical bowls, it aims for a contemporary display voice that feels engineered and durable.
The typeface reads best at larger sizes where its tight counters and closed-in apertures remain clear; at smaller sizes the dense shapes can visually plug up. The rhythm is strongly modular, with repeated rounded-rectangle motifs creating a uniform, stamped look across uppercase, lowercase, and numerals.
