This is a machined aluminum pen shell for the replaceable Sharpie markers. It includes the following:
- Main body and cap
- Leather lanyard & Pocket Clip (these can be removed from the pen cap)
- Small tail attachment (Seen on the pen body)
- Large tail attachment
- Pointed/Spike tail attachment (seen with clear tubing over the sharp point to protect user)
This was a Kickstarter project I backed a couple years ago. Interesting idea, but I never really had much use for it.
