The creator, shop owner Christy Grierson, came up with the idea after listening to her customers complain about cardigans without closures. What they needed was a safety pin—but who wants to ruin a great look with a safety pin? Christy started tinkering with heavy-duty magnets and adding embellishments to make them more fashionable. Her designs were an instant hit, ranging from classic, subtle patterns to more expressive, bold prints.
