This typeface is a heavy slab serif with square, flat-ended serifs and terminals that give the forms a blocky, engineered feel. Strokes are consistently thick with minimal contrast, and the curves (notably in C, G, O, and S) are broad and controlled rather than calligraphic. Proportions are fairly compact with tight apertures and counters in several letters, producing a dense, emphatic texture in text. The lowercase is sturdy and straightforward, with short-looking ascenders and descenders and a compact, utilitarian rhythm that holds together well at larger sizes.
It works best for display settings where a strong, authoritative voice is needed—headlines, posters, packaging, and signage. It can also support editorial pull quotes or short blocks of text when set with comfortable leading and spacing to offset its dense typographic color.
The overall tone is robust and no-nonsense, evoking industrial signage and mid-century editorial display. Its weight and squared detailing project confidence and durability, with a subtle retro flavor that feels practical rather than ornamental.
The design appears intended to deliver maximum impact with a pragmatic slab-serif structure: square terminals, firm geometry, and consistent stroke weight create a dependable display face that reads as strong and utilitarian.
The numerals are equally heavy and geometric, matching the squared serif language for a cohesive set. In continuous text the dense color and tight interior spaces suggest it will feel most comfortable when given a bit of breathing room through size or leading.
