It is PSI's Patrizio kit. I really like the way the kit looks. It is not the most comfortable to write with, but it really does make a nice looking pen. Also, because the tubes are so short, you can get three barrels out of a blank, so two blanks can make three pens. Or as with my first attempt at leadwood, it gives you a spare piece to remake a barrel when you jam your transfer punch into the transmission in an attempt to remove it.
