Filofax Pocket Transparent Zip Lock Envelope

"I'm a German fountain pen lover, and the Aero is one of the best pens I've found. The steel nib writes smooth right out of the box, and while there's some heft to this pen, there's also an exquisite balance that just makes it work. Also, the price offered by Fahrney's on this pen could not be beat -- outstanding value for the money. This was a great purchase and addition to my pen collection, through and through." - Verified Buyer, November 2025
