ZCOOL Qingke Butter

Butter Ti is type as soft-serve: every terminal rounds off, no corner survives, hooks curve like cream through a piping bag, and squashed low-gravity bodies read adorably dopey. Commissioned by IoT company MXCHIP for its device UI and released free through ZCOOL's charity series, it carries both decorative charm and interface bones in one file. Full GB2312 plus Latin ships in one weight, and the Google Fonts edition (ZCOOL QingKe HuangYou) makes web use trivial. Round terminals melt together at small sizes, so reserve it for display - the one physical law shared by all buttery faces.

Tech notes: Butter is deliberately a bold round (not a hairline rounded), terminals share one radius, the slashed zero prevents confusion; punctuation is full-width centred, mind baselines against Latin quotes. Several consumer brands set packaging in it - and lookalike paid counterfeits exist, so trust the ZCOOL series page for the file.

Sweet for bakery, tea and dessert packaging, kids and pet brands, app empty-states and achievement popups, greeting cards, meme captions. Rules: nothing under 18 px of body copy; headlines and buttons of up to four characters are its golden zone; macaron palettes love it, compliance documents do not.
