Barack Obama’s favorite pen: The former president weights in on an extraordinarily contentious topic.

All the President’s Pens — Slate on Barack Obama’s Favorite Pen

Barack Obama, no stranger to controversy, waded into an extraordinarily contentious area of American life on Wednesday when he revealed his pen preferences. The former president told the New York Times that when composing longform writing, including his recent book A Promised Land, he prefers to sketch out his first drafts by hand, rather than on a computer. What’s more, like all true stationery nerds, Obama is “very particular” about his writing tools, preferring the combination of yellow legal pad and black Uni-ball Vision Elite rollerball pen with a micro-point.
