Space Saver: Four-in-1 Ruler Pen

Back-to-college season has us fixated on writing implements at the moment, and few can compete with the economy of the 4 Function Ruler Pen, which manages to be pen, pencil, highlighter and stylus in one—and can also do duty as ruler in a pinch. Developed by Adrian Olabuenaga, the slender device makes it possible for the user to switch amongst the 4 choices by holding the pen horizontally and rotating it until every single corresponding icon tends to make its look. And the vibrant yellow colour tends to make it straightforward to spot in any overstuffed bag, as well.
