This is the integrated stylus from an ASUS BR1100FKA, which rests inside of its own garage in the left side of the laptop, and contains a battery.This stylus is MOSTLY UNTESTED. It was functional when I used it, but the battery life on it has the potential to be bad-- I wasn't able to test it for long enough to see.The stylus and its tip/nub you see in the photos are the same items you'll receive.Feel free to message for any questions.
