As avid readers, you don't need us to explain the benefits of a bright, compact book light. But our Pen Clip Light does more than slide onto a book cover to illuminate your reading material; it also fits neatly on the end of a pen or pencil, making writing in dim light that much easier. With its adjustable head and accessible on/off switch, the Pen Clip Light will provide hours of focused LED-light radiance. We're offering a set of two of these indispensable little tools; share with a friend or stash the extra in your car, art box, or equipment bag!
