This is a heads-up on this cheap $2 pen which i have shown earlier. while it is cheap and writes well, but it has a major flaw; it is a cartridge killer.
I have put in one long cartridge initially, standard international, and it worked for a while. after a couple of weeks, the pen suddenly leaked on first writing, and i realise that the cartridge's mouth had split. no matter, could be a cartridge issue, so i had it swapped to another short international cartridge. same thing happened, it was working initially, then the cartridge's mouth split opened. the pen leaked and created a whole mess. I am now trying the china standard international cartridge, or the daiso pen refill, which has a bigger mouth and seems to be made of a sturdy material, but i'm not betting much money on it. and no way am i going to sacrifice a converter.
my verdict: buy the pen for the nib, stay clear of using it. the grip isn't very good btw too.
