A heavy, monoline serif design with thick strokes and prominent slab-like feet that are consistently softened into rounded corners. Curves are broad and smooth, joins are sturdy, and the overall drawing favors blunt, bulbous terminals over sharp cuts. The uppercase feels compact and solid, while the lowercase keeps a generous, readable structure with a single-storey “a” and simplified forms that emphasize weight and clarity. Numerals are wide and substantial, matching the letterforms’ rounded slabs and even color.
Well suited to headlines and short blocks of text where a bold, friendly voice is needed—such as posters, product packaging, café/retail signage, and brand marks. It can also work for pull quotes or section headers where a dense, rounded serif texture helps create emphasis without feeling formal.
The font projects a warm, approachable tone with a distinctly retro, print-like flavor. Its rounded slabs and chunky rhythm feel friendly and slightly playful, while the dense stroke weight adds confidence and durability.
The design appears intended to combine the authority of slab serifs with softened, rounded finishing for approachability. It balances a sturdy, print-forward structure with playful terminal shaping to produce a memorable, highly legible display text face.
Spacing and sidebearings appear tuned for even, dark texture in paragraph settings, with distinctive slab cues (notched-looking joins and rounded feet) giving words a recognizable silhouette. The sample text shows strong presence at display sizes and a pleasantly uniform color across lines.
