38 Twist Action - 110 Copper - Pentel Energel 0.5mm Needle Nose
I have been getting lots of requests to bring back some copper twist pens back! I have made a few extras on top of the pre orders that have shipped out and I am offering those now.
Copper is unlike any other material out there. This material is C110 Copper (99.99%) and it is difficult and picky to work with. The machined finishes glow. The weight and feel is super satisfying. 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 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 Pentel Energel refill. 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.
