Inspired by the steam engine, this pen reliably extends and retracts using a steampump action click mechanism. Featuring an intricately cast Victorian clock surrounded by gears and pipes, a machined tip decorated with leaf trim and a "through-holed waist" that gives a view to the inside of the pen, and a curved, machined and precision-engeneered pen clip with routed edges, through-holes, and rivets. This pen is a must have for any Steampunk enthusiast or collector!
