Hi Folks, I just bought a used pen on eBay that had the description "works very well". After cleaning it, I tried to ink it up with both a converter and a cartridge. Neither would seat in the pen and the ink leaked out all over. The seller offered me less than half the value of the pen + shipping, without return shipping. I refused the offer and told them that I would be opening a case with eBay and also leaving them a bad review. Any advice, other than to buy only from known sellers going forward? Out them by name here? Is there a thread in FPN where complaints and praise is found?
