A extremely unique TIMELESS Steampunk ball pen made to represent the  30 mm GAU-8 Avenger rotary cannon install only in the FAIRCHILD REPUBLIC A-10 Thunderbolt II aka Warthog or Hog. 

As the name suggested, the pen is heavy but at the same time `well balance to give the owner the power to write for hours!

This writing instrument uses a Parker or Cross ink refil
