Serpent Twist Pen in Antique Brass Finish with Zebrawood Body

A Serpent theme twist pen in Antique Brass finish, with a Zebrawood body. The pen uses a standard Parker style ball point pen cartridge (black ink included). The pen as shown is just over 5.5" long, and just under 0.6" diameter at the widest point.

To use the pen, the ink ball-point can be extended and retracted by twisting the upper and lower halves of the pen. To change the ink cartridge, unscrew the upper barrel from the lower barrel, past the retract point. Remove the old cartridge, and transfer the spring from the old cartridge to the new cartridge, small end first. Insert the replacement cartridge into the pen body, and then screw the upper body of the pen back onto the lower body.
