I've talked about ink cartridges and filling mechanisms already in the Fountain Pen 101 series, and I want to build upon that with today's tutorial on refilling empty ink cartridges.
Why would you refill ink cartridges?
To save money, so you don't have to buy a converter for your cartridge/converter pen
Higher ink capacity, some cartridges have higher ink capacities than their matching converters
More ink options, as some pens only take cartridges like the Kaweco Sport and J. Herbin Rollerball pen
There are just a few things you'll need to refill your ink cartridges:
A pen that takes cartridges
Empty ink cartridges (you'll need to save these, as you usually can't buy them empty)
At least one ink syringe, two make the process faster
That's it! You're essentially just flushing the dirty cartridge out with water and refilling it with ink. This process isn't quite as convenient as filling a pen with a converter, but it can be really helpful in certain situations!
There are also a lot of other great uses for ink syringes, see my video on them here.
