Yes, it's true: your grubby fingers can smudge up otherwise clean touch screens. But with a Touch Screen Pencil, your fingers stay on your stylus. As a touch screen stylus, this rubber pencil works with both touch screen types, capacitive and resistive, and so works with a multitude of gadgets. As a precision instrument, the touch pad pen also gives you an advantage in touch screen games, drawing programs, texting, clicking, and other functions. As a rubber tool, it's also over-sized for easier handling because, let's face it, your grubby fingers are just that. At least a Touch Screen Pencil can help with everything else!
