Cartridge/Converter vs Piston Filling
The fundamental filling-system fork: modular convenience or built-in capacity?
Option A
Cartridge/Converter
Choose cartridge/converter for flexibility — cartridges when traveling, bottles at the desk, trivial cleaning, and the widest pen selection at every price.
Option B
Piston Filler
Choose a piston to commit to bottled ink — two to three times the capacity, no parts to lose, and the small ceremony that makes filling a pleasure.

| Cartridge/Converter | Piston Filler | |
|---|---|---|
| Capacity | ~0.5–1.0 ml | ~1.5–2.0+ ml |
| Travel | Carry sealed cartridges | Fill before you go (or carry a bottle) |
| Cleaning | Fast — flush or swap the converter | More cycles; demonstrators show residue |
| Ink freedom | Bottles via converter | Bottles only |
| Long-term | Converters are cheap replaceables | Seals serviceable on good pens |
| Best for | Beginners, travelers, ink-changers | Journalers, volume writers, ritualists |
The bottom line
Most collections end up holding both: c/c pens for rotation and travel, one piston workhorse inked with the house blue-black. Start c/c; add the piston when one bottle becomes "your ink."
