Over two years ago, I made a video on flushing your cartridge/converter fountain pen with a bulb syringe, which is easily the single best trick to improve your fountain pen cleaning experience. I wanted to update the video to include it in the Fountain Pen 101 series, as well as include a bonus trick for flushing pens like the Namiki Falcon and Sheaffer 100 that don't flush well with a bulb syringe.
