Wacom Bamboo Stylus Duo CS-170 3rd generation, touch screen stylus for iPad, iPhone, Android Tablets, Smartphones with replaceable Pen Carbon tip and ballpoint pen, gray (Accessories)
After me the input pins on Amazon last ordered (Kamor, Liamoo, ...) all had not really convinced, I have decided to increase the price range a little. The pin slides easily across the screen (without protective film) and allows a very precise input.
