This is the green circuit board blank from the regular Sierra Vista Circuit Board Pen Kits. This is a real but non-functional circuit board. You can use this blank with any of the Sierra Vista or Sierra Vista Stylus Pen Kits.

With great care while turning (you will need to make the pen with slight bulges and possibly rounded edges) or trimming (be very conscious of the diameter of the pen kit you are using when trimming the blanks to length, don't try to put a large circuit board componant where you need the blank to be its thinnest) you can also use this pen blank on the following kits:

- Cigar Pen/Pencil Kits (Needs two blanks, cigar tubes glued into the sierra tubes, and the blanks need to be shortened.)
- Sierra | Virage Twist Pen Kits
- Old Style Sierra Button Click Pen Kits (The ones with the chrome extension pieces for the refill. That extension piece will need to be shortened by 0.2")

They will not work with the New Style Sierra Button Click Pen Kits because the blanks are 0.15 inches too short.
