Sailor pen cartridge hacks

In which I quickly modify a international cartridge piston converter from a cheap Jinhao pen to fit in my sailor fude nib fountain pen. I then also use a silicone drinking straw as a refillable cartridge as well.

I don't know if I'd trust the seal long term on those but it's pretty useful! Thanks for the research and innovation.

i'm planning on buying one of these sailor fude pens so this is very welcome tip. have you had any accidents with that hacked converter since you posted that video? i wonder if it would be more secure if you would put a bit of teflon tape around the opening
