A heavy, rounded sans with superellipse-driven bowls and corners that read as softly squared rather than purely circular. Strokes are broadly monolinear, with thick joins and generous interior shapes that keep counters open despite the weight. Proportions are compact and sturdy, with a tall x-height and short ascenders/descenders that create a dense, blocky texture in text. Terminals are blunt and squared-off with rounded edges, giving the letters a molded, cushiony silhouette; diagonals (A, V, W, X) are wide and stable, and round letters like O/C/G lean toward rounded-rectangle geometry.
Best suited for headlines and short blocks of copy where strong presence and friendly geometry are desirable. Works well for branding, packaging, posters, and signage that benefit from a soft, modern bold voice. In longer passages it will read as highly emphatic due to its dense weight and compact proportions.
The overall tone is bold and approachable—assertive in color but softened by rounded corners and friendly proportions. It feels contemporary and upbeat, with a slightly toy-like, poster-ready warmth that avoids harshness. The rhythm in words is punchy and energetic, making it well suited to attention-grabbing messaging.
The design appears intended to deliver maximum impact with a softened edge: a sturdy, highly legible bold sans whose rounded-rectangle construction creates a distinctive, contemporary character. Its tall x-height and open counters suggest an emphasis on clarity at display and medium text sizes while maintaining a playful, approachable feel.
At display sizes the distinctive superellipse curvature is especially clear in the bowls and shoulders, while in paragraph settings the dense weight creates strong emphasis and a compact grey value. The numerals are similarly robust and simple, matching the rounded-rectangle construction of the letters for consistent texture across mixed copy.
