With a couple of exceptions, I note that inks come in bottles that don't seem particularly well suited to the dipping and refilling of pens. They're difficult to fill and a pen when the ink in the bottle starts running low.
When I was a kid my mom had cool shceaffer snorkel. The ink had a "side pocket"reservoir that you tipped to fill (while the bottle cap was still on). This filled the side pocked and made the filling of the pen efficient and pain free.
Do any of you use a dedicated ink bottle that's easily filled?
