I shall definitely look into that next time I'm in civilisation. Thank you!
It's surprising the rollerball leaked. Did that happen with several cartridges or just one?
Incidentally, I've just bought a new cartridge just in case I had a dodgy cartridge, to try it out on my next flight (although maybe I shouldn't test it on a 14-hour flight first

). I was a bit surprised that it leaked too. It didn't leak too badly, but was still a leak.
