Oh Bill!!!

Sorry! I had a laugh at your expense!

Sounds something like what I would do, however!
I agree- the idea of pressurizing that little vial with the ink sitting at the bottom with only a press-seal doesn't sound like the best thing to do.

If I go ahead with the pruchase, I'll try it out with water in any pen I hope to use it with...
@Hans-Peter: Thanks for your discussion as well! I definitely can get by with an ink bottle, but it does take up quite a bit of space in my already over-stuffed insane bag.

So, going small is always a nice thing. It's too bad that Namiki doesn't produce a similar product for the VP's... they have a very limited ink Capacity, and the ability to refill would do wonders for that little guy. [Oh how I love my new VP!] I guess I can alway keep a spare cart around... but to be honest, I'd rather not use 'em. I'd rather use the ink that's already in the feed etc.
I could definitely use some of the little Nalgenes, and should likely pick up a few just for this purpose.
It actually wouldn't be too hard to produce a neck similar to the visconti rubberized neck for small bottles... the only thing I can't figure out too well is how to make a nice seal to the top of the vial so that it won't easily be pressed inwards, or allow ink to seep around it. Perhaps if I get the inkwell, I'll do a bit of discovery on how they solved the problem. Perhaps that'll give me some ideas as to how I could solve the problem.
Of course, I could always bond directly to the glass with a silane of some sort... and using a silicon rubber form, could make the neck that way... seems like a lot of effort for a conical rubber gasket. Hmm... well, if I can get my Preliminary Examination over with soon, I'll dig around some of the gasket suppliers and see if they have an annulus with a sloping inner diameter of various sizes that migth fit a glass vial...
Thanks for the thoughts, guys! I appreciate it. At least I know the ink-pots work really well with some pens- especially the pistons.

My best to you guys this evening!!
