A stylus that absorbs electricity for use on modern smartphones, tablets and other capacitive touchscreens. Also called a "touch pen," many people find using the stylus more comfortable than tapping and swiping with their fingers, no matter whether they have big or small hands. See stylus
The white pen is both a stylus and ballpoint pen, while the red and green styli are only for touchscreen use. The spongy tips absorb electricity like human fingers do.
