Tantrum (San Francisco): TANTRUM is a curated whimsy filled with kid-centric well-designed gifts for kids and grown-ups alike. an imaginary world of times passed. child-like, magical, nostalgic, and marvelous are the items that fill this unique and amazing space. part carnival, part storybook, part memory. TANTRUM opened in June of 2012 from a love of carnival energy and mid-century design. pay us a visit when in San Francisco!
