Montblanc Piston converter for StarWalker Fountain Pen

"This is now my go to everyday pocket pen. The nib is buttery smooth and there is something that is just surreal with the feel of the cap going on the barrel when you post it. The small ink supply is worth it with how well this pen writes! Fits in any pocket. Highly recommend if your looking for a small pocket pen that is anything but when posted." - Verified Buyer, September 2025
