Diamond Knurl Ballpoint Pen Kit - Black Chrome.

The newest pen kit from ExoticBlanks, the Dashing Diamond Knurl! A very special variation of the one piece ballpoint pen kit. 

We bring our experience with pens to the design table, here. The new Diamond Knurl design sparkles in the light, commanding attention in any crowd! Available in a number of platings, all focusing on enduring beauty, with all the functional advantages of Exotics' earlier, pen kit designs -- The Ellipse and the Zodiac.

  • Extremely easy to make pen kit - single tube, with interchangeable ends (straight body)
  • Multiple threaded joints allow you to design the pen for "Nib refilling", solving the problem of the transmission moving when the refill is changed.
  • Well balanced for comfort and ease of writing.
  • Uses premium Parker type refill including gel refills or the exceptional Schmidt 9000 refill
  • Very attractive elegant shape.
  • Uses the same bushings, tubes, and tools as the Sierra Pen Kit.

Kit Includes -

  • Pen Kit Components (Pen blank not included)
  • Parker Style Ballpoint Refill
  • Brass Tube

    To be honest, the directions were a tad long-winded. After you get through those, the pen is a snap to assemble. AS easy as any pen kit I have put together. I will definitely purchase more of this kit.

    Really like the all-black pen kit. I use them for my custom blanks and my customers really like them. I haven't had any problems with this kit.

    I gave a friend one of these to carry every day and report back. The black chrome has held up very well for over 5 months so I will be adding this to my line up.
