A sturdy slab-serif design with squared, unbracketed serifs and mostly flat terminals that give the letters a rectilinear, engineered feel. Strokes stay fairly even with low contrast, while counters are open and clearly shaped, especially in the round letters. The uppercase shows a controlled, slightly condensed rhythm with strong horizontals on E/F/T and a wide, circular O; the lowercase keeps compact proportions with a single-storey a and g and a pronounced, horizontal ear on r. Numerals are clear and upright, with simple forms and strong baseline presence that match the text color of the letters.

Well-suited for editorial typography, headlines, and subheads where a strong, steady text color is desirable. It can also support branding and packaging that benefit from a dependable, heritage-leaning slab-serif voice, and it scales effectively for posters and short blocks of copy.

The overall tone is practical and no-nonsense, with a confident, workmanlike presence. Its square serifs and firm terminals evoke a retro-industrial and editorial voice—clear, direct, and a bit authoritative rather than delicate or expressive.

The design appears intended to deliver a robust slab-serif look with clear reading shapes and a firm, squared terminal style. It prioritizes consistency and impact, aiming for a dependable, print-friendly texture that feels both classic and industrial.

The family’s visual identity is driven by the consistent slab treatment and the crisp, squared-off joins, which create a uniform texture in paragraphs. Round characters remain smooth enough to avoid looking overly mechanical, balancing rigidity with readability.
