A heavy, blocky sans with broad, squarish rounds and strongly softened corners. Curves tend to resolve as rounded-rectangle shapes, giving O/C/G and the bowls of B/P/R a superelliptical feel rather than a purely circular one. Terminals are blunt and squared-off, joins are smooth, and the overall rhythm is steady and dense with relatively tight inner counters. The lowercase is simple and sturdy, with single-story a and g, a short-armed r, and a sturdy t; numerals are equally chunky with a rounded-rect 0 and a compact 8.
Best suited to display settings such as headlines, posters, logos, packaging, and punchy signage where strong impact and a friendly voice are desired. It can also work for short callouts or UI labels in bold, playful branding, but it is less comfortable for long passages of small text due to its dense interior space.
The overall tone is bold and approachable, leaning toward a playful, retro display voice. Its soft-cornered geometry reads friendly and informal, with a slightly toy-like, cartoon headline energy rather than a neutral utilitarian one.
The design appears intended to deliver maximum presence with softened, geometric forms—combining a sturdy, billboard-like weight with rounded-rectangle construction for a welcoming, characterful display style.
Wide, flat horizontals and large, rounded bowls create a strong silhouette at large sizes. The compact counters and heavy joins can visually fill in at small sizes, making it feel best when given space and size for the shapes to breathe.
