This pen features a unique bolt action mechanism to extend and retract the ink cartridge. The clip is a bolt action rifle, the finial replicates the look of a 30 caliber cartridge, and the nib replicates a 30 caliber bullet.
The body is turned from a hybrid combining pieces of walnut shell with resin. Note that the walnut shell is not exposed for contact. The finished body has had a durable finish applied that seals in the walnut shells.
This pen takes Parker-style refills.
