I had read some reviews which sugested there would be some risk in this purchase. But everything has turned out just fine. These pens are brand new, in their original PALM packaging, and they FIT PERFECTLY into my Treo-650 (which I also just purchased from Overstock). These pens have a screw-on/off tip, which exposes a fully functioning ink pen, (which I suspect I will only use in restraunts when the waiter forgets to provide a pen for the credit card receipt). Also these pens have a screw-on/off "top", which might be there to exchange with another shaped top for another Palm device. If you have a Treo-650, THIS item is the right choice. ... OTHER reviews I had seen for SIMILAR stylus's here on Overstock seem to present the risk that they would not fit some treos.
