I was just cruising around looking for an Onoto Plunger Filler that did not cost as much as my first car (only sort of kidding) when I came across a limited selection of the NEW P.w. Akkerman Ink at fountain pen recycler.com
They currently stock #5, 8, 11, 13, 28, and 30. You can find the bottles at their "new to website" page = http://www.fountainp...TO OUR WEBSITE!
I hope I did not break any rules by doing this, and if I did, please point it out!
Also, I am not endorsed by the company, just a soon to be customer. (but, ya know, I bet we could work something out with an endorsement!)
