The pen is made of acrylic resin. (probably not precious, though!)
I've been using Franklin-Christoph JoWo nibs in my Moonwalk Pen for the past year, and with good results. I really haven't gotten far on nib options for this pen. Clearly any JoWo unit will screw right in, and I can easily get nibs from F-C in a variety of widths and even in 14K if someone wants to pay the price.
