36 Click Pen - C110 Pure Copper Body - 6Al-4V Titanium Clip - Step Nose - Borosilicate Ball - Pentel EnerGel
Made out of the incredibly beautiful pure 99.9% C110 copper and very tough 6Al-4V titanium. Raw machined copper looks unlike anything else but is very difficult to machine. Copper can be maintained shiny, or let to achieve a patina that shows the signs of its use. A single 0.36" (9.14mm) diameter grip and a stepped nose section. The mechanism comes equipped this time with a clear borosilicate ball that I have never offered before.
No batching ensures all of the parts fit perfectly together. Unparalleled warranty to ensure that you are entirely happy with fit, function and finish. The clip takes an excessive six individual operations to create a unique one piece clip and click mechanism.
Tip bore drill is aligned and offset with great care and is machined to a tolerance of just 0.001" or 25 micron to hold the 2.3mm tip of the Pentel EnerGel perfectly without any wiggle. Solid material is drilled out with a carbide drill perfectly true over an extreme diameter to depth radio, in order to fit the refills tightly without rattle.
Click the button down and then return it by pinching the mechanism between your fingers, and the button will snap back. Threading has a high quality higbee start to make replacing the refill super easy.
