Kaweco cleaning syringe
Don't know how to properly clean your fountain pen? Then Kaweco has a solution here: the cleaning syringe. This has been proven in Kaweco's service for years. Consisting of a standard syringe with a blank cartridge as a tip, this is an excellent way to flush all fountain pens that need to be filled from the cartridge base.
The syringe provides enough pressure to flush out ink residue from the ink conductor and the empty cartridge allows it to be placed properly.
