Converter/Cartridge Compatibility Guide
- Piston Converters - Utilizes a twisting motion to push air out and then pull the air/ink back when twisting it counter clockwise.
- Squeeze Converters - Utilizes a squeeze mechanism on the bladder to pull ink out from the bottle
Standard vs Proprietary Converters/Cartridges
- Standard International - Standard size that will fit most fountain pens that don't use a proprietary converter/cartridge (ex. Monteverde)
- Proprietary - a converter or cartridge that is brand specific to fit a specific model or brand (ex. Lamy)
Note: While a majority of fountain pens use the standard international converters or cartridges, some models may not. This fountain pen converter/cartridge guide is meant as a recommendation. Please refer to your specific pen’s instructions for acceptable converter/cartridge sizes, or feel free to contact us at firstname.lastname@example.org or call us at (410) 992-3272 if you have any questions.
