Filling Systems
Cartridge, converter, piston, vacuum, eyedropper — capacity vs ceremony.
How a pen drinks shapes how you live with it. Cartridges travel; converters unlock bottles; pistons carry a week of writing; vacuums fill with a thunk; eyedroppers turn the whole barrel into a tank. We map each mechanism’s capacity, mess factor, and maintenance honestly — including the ones we’d skip.
