A heavy slab serif with sturdy, blocky construction and softly rounded corners throughout. Strokes are broadly even with minimal modulation, and terminals resolve into thick, squared serifs with gentle bracketing that keeps the shapes from feeling sharp. Counters are relatively tight for the weight, giving letters a compact, punchy texture, while overall spacing remains readable in continuous text. The lowercase shows simple, workmanlike forms with single-storey a and g, and the numerals match the same solid, blunt rhythm.
Best suited to headlines and display settings where its weight and slabbed structure can deliver impact without losing clarity. It also works well for packaging, signage, and logo wordmarks that benefit from a sturdy, retro-leaning voice; for longer text, it performs most comfortably at larger sizes where counters and spacing have room to breathe.
The tone is dependable and upbeat, combining a practical, industrial voice with a distinctly vintage, print-era warmth. Its chunky presence feels confident and approachable, suited to messaging that wants to read as bold, straightforward, and a bit nostalgic.
The design appears aimed at a no-nonsense slab serif that prints with strong color and consistent rhythm, prioritizing legibility and presence over delicate detail. Rounded joins and bracketed slabs suggest an intention to feel robust yet friendly, echoing classic advertising and sign-painting influences while staying broadly usable.
In the sample text, the dense color and soft-edged slabs create strong word shapes and clear emphasis at larger sizes, with a consistent, poster-friendly rhythm. The round letters (C, O, S) and the slabbed verticals (I, H, N) balance each other, producing an even, stable line in paragraphs.
