I refilled an empty cartridge of a ballpoint pen with regular ink, but now the pen doesn't work.
- Why is that?
- How to refill the cartridge of ballpoint pen properly?
- What substance could I mix the ink with in which concentration to make the pen work again?
I want to avoid having to throw away so much plastic as even if I buy a new cartridge that still produces far too much waste.
The ballpoint pen I tried to refill is a 0.7 mm Frixion, and I am open for suggestions of other pens that are easy to handle (so my hands won't hurt after some minutes of writing), wasn't able to find any at the local stores I visited lately...
