I really should read this again.

This looks like a great way to fill a pen, thank you for suggesting it!

There’s a lot to be said for a reliable, inexpensive ink that goes well with multiple pens! I must get myself a bottle.

I need to start experimenting with inks. Currently Montblanc Permanent Black goes into all of my pens, although I’m waiting on a Pelikan M800 which will come with a bottle of Pelikan 4001 Black, which I’m very much looking forward to writing with.

Great reply!

Thank you @jadero, that was a very useful answer!
