Steampunk Bolt Action Pen:
The Steampunk Bolt Action pen uses a Parker® style refill. The parker-type black ink roller-ball pen is propelled by the bolt at the top of the pen, just as one would load a real single action rifle.
The pen refill can be changed by twisting the bottom of the pen and unscrewing it completely.
Remove the old refill and spring, replace the new refill in the spring and insert into the bottom of the pen and screw back onto the body of the pen.
