It has almost everything that you will need for your day to day office/home needs. It has a ballpoint pen that you can replace yourself using other cheap pens innards. The refill is not your usual refill stuff like Parker's. It has a pencil, which is also refillable and a PDA stylus that works brilliantly well. Dont expect it to work on the capacitive screens PDA as it is designed for the resistive type. Capacitive screen are the screens of IPhone, HTC desire, wildfire and most PDA with "swipe" features. It will never work on those. Works well with the old, PDA, resistive screen though and that what its made for. You will notice that the pen is bit bulky for your normal on shirt pen holder, but it sits well on your finger when you use it. The plastic body of the pen looks brittle but it wasn't. Was able to support my weight when I accidentally sat on it without breaking. Of course it is still plastic so dont expect too much...
