A rounded, monoline sans with softly tapered stroke endings and gently squared joins. Curves are smooth and broadly circular, with open apertures and generous internal counters that keep letters airy at text sizes. Proportions are balanced and unforced, with slightly humanist construction in shapes like the lowercase a and e, and straightforward, legible figures. Overall spacing reads even and calm, with a consistent rhythm across uppercase, lowercase, and numerals.
It suits interface text, product copy, and general-purpose editorial settings where a clean sans is needed without a rigid, geometric feel. The open counters and rounded terminals also make it a good choice for approachable branding, wayfinding, and short headings that need to stay friendly while remaining highly legible.
The tone is approachable and contemporary, prioritizing clarity over display character. Its rounded strokes and open forms give it a warm, non-technical feel while still reading as neutral and professional.
The design appears intended as a versatile, everyday sans that emphasizes legibility and a gentle, modern personality. Its restrained detailing and consistent stroke treatment suggest a focus on reliable performance across a wide range of sizes and contexts.
Distinctive features include a single-storey lowercase a, a compact, open lowercase e, and a two-storey g with a rounded lower bowl. Numerals are simple and readable with smooth curves and minimal stylistic quirks, supporting quick scanning in mixed text.
