Go seamlessly between pixel and paper with a stylus pen! Created specifically for use with touch-screen devices, stylus pens come in many shapes and sizes. There are two main types of styli: the capacitive stylus, which conducts bio-electricity from your hand to the screen, and the resistive stylus, which applies pressure to certain points the screen.
