38 464 Brass - Pilot G2 (Rollerball)
This pen is exceptionally sturdy and the 464 brass is the toughest material I offer right now. Even weight distribution with excellent finish on the tube with slight texture from the machining lines. Has a hefty feel and is great to write with. Clean machined finishes right off of the machine.
Twist mechanism with triple start screw thread is super simple and reliable. Carbide drill makes the hole in the tip at very precise tolerance of 25 micron. Comes with a very smooth writing rollerball style Pilot G2. I pay very close attention to the tolerances and surface finishes. 5-1/2" (140mm) long and 0.36" (9.1mm) in diameter. 42g (1.48oz) in weight.
