You said you just filled the whole pen up with ink...but you also said it came with an o-ring?
Mine don’t have no o-ring!!
:-(
Heh heh!
It was converted for me - this is the one that comes with the Noodler’s Ink - Nathan Tardif (who basically *is* Noodler’s) does ‘em up. Pendemonium also sells the eyedropper converted ones, but I don’t know when they’ll have them in stock.
It’s probably a simple conversion, but I don’t know where the pieces come from.
