Tactile Turn Bolt Action

Machined pens make in Texas. Of course I only own the Ultem version. This is the full size.

Variants: Bolt action in two widths & three lengths. They also have side click pens.

Refill depending on variant: Parker-Style G2, Pilot Brand G2. Hacked Pilot-style G2 refills will fit the short pen made for Parker-style G2.
