Kaweco Ink Cartridges are available in international standard cartridge size and are thus compatible with any fountain pen.

Just unscrew the front part insert with the nib, extract the empty ink cartridge, insert the brand new Kaweco cartridge, and you are ready for new writing experiences. All Kaweco inks are cruelty-free and vegan.

Each cartridge contains approximately 1ml ink

Tip: To avoid unsightly color contamination when changing the color of the ink cartridges, we recommend our Kaweco cleansing syringe for quick and thorough cleaning of the pen.
