While it has been a long time, I have been very busy.
It is a "European Style" or "Dome-Top" twist ballpoint pen. The hardware is finished in Black Titanium with a single Chrome/Rhodium ring. The barrels are made of Dark Blue Invisavue which makes it impossible to see through the acrylic to the brass barrels and finishes very strong and durable. The plastic also is marginally more flexible and rubbery than acrylic which reduces chances of cracking in severe cold and scratches overall.
