Wanna deck out your Fellhoelter pen? You can spec out yout TiBolt pen, or add some sweet detail to your pens with an engraved bolt group. Comes with a titanium Dragon bolt barrel and bolt handle.
Note: Neither Fellhoelter or your pals at Monkey Edge are responsible if ya bugger up your pen. You do need a bit of handiness to unscrew your existing ball from the bolt mech. Don't get all gorilla and end up breaking it.
