Mine leaked from the right side of the nib first then from the breather hole on the bottom of the pen. It was a mess. Don't use it anymore. First pen I bought strictly for the aesthetics. Bad idea!
I suggest a converter or cartridge seating problem.
If the section isn't full, and it is a slow or non starter, will just a filling fix it?
Ensuring the section is full, then yes.
Back to the topic,
Anyway, if a pen were that bad you would not be promoting it...post #60
