Is the cartridge coming with Preppy really too short to reach the back of the barrel? Never seen that in a fountain pen and looks unnecessarily risky design. I am wondering if the vendor sent me the wrong cartridge.

      Interesting. All of mine hit the back. I always thought that was meant to push the cartridge in and secure it there. The neck may be tight but a long cartridge can’t possibly move. Eg I notice Lamys are sold with a removable ring that stops you fully tightening the barrel by accident and breaking the seal of the cartridge that come’s with the pen. I don’t see why designers would choose not to secure their proprietary cartridge like that, unless they want to be able to design shorter models and use the same cartridges.

        @Stopwatch1986 Ah, you’re right about the Safaris! Most cartridges are made to fit inside as many pens as possible, so there aren’t many that work that way. The way they fit is strong enough that it takes a fair amount of force to dislodge it, at which point I’d be more concerned about the state of the pen than if the cartridge has been knocked loose.

          All my pens that take two international cartridges back-to-back do that too, otherwise they would rattle if you shook them.
