A heavy, rounded sans with monoline strokes and fully softened terminals throughout. Letterforms are broad and open with generous counters, minimal contrast, and a slightly irregular, hand-drawn steadiness that keeps curves from feeling mechanical. The capitals are sturdy and simple, while the lowercase has single-storey forms and compact, rounded shoulders; punctuation and dots are circular and prominent. Numerals are similarly bulbous and clear, matching the overall soft geometry and consistent stroke weight.
Best suited to headlines, short UI labels, packaging, and branding where an upbeat, friendly presence is desired. It also works well for children’s materials and playful posters, and can hold up in short paragraphs at larger sizes thanks to its open counters and straightforward forms.
The overall tone is warm and approachable, with a cheerful, kid-friendly energy. Its rounded shapes and cushioned corners create a lighthearted, informal voice that feels conversational rather than corporate.
This font appears designed to deliver a soft, approachable display voice with strong legibility, using rounded terminals and simple construction to create a friendly, modern feel that stands out without relying on ornament.
Spacing appears comfortable and even in the paragraph sample, supporting solid readability at large and medium sizes. The design favors clarity and charm over strict geometric precision, giving it a personable, cartoon-adjacent flavor without becoming overly decorative.
