Hello. This is my first post to the forum. I'm a very recent freshly minted fan of FP's and I have a bit of a question.

Last week I picked up a cheap Yafa ink cartridge FP from the local office supply super store for $13. It pales next to the Lamy Safari (charcoal w/ medium nib) that finally arrived via post yesterday, but I'm hoping (perhaps in vain) that it can be made a bit more serviceable by running better ink through it.

My Lamy does have a converter that I bought with it, and I am running some Noodler's bulletproof black ink through it. I'd like to run the same ink through the Yafa pen. Is there such a thing as a converter for this pen?

In the meantime, I have FP #3 on it's way, a Lamy Al-Star (aluminum finish) with EF nib. I'd like a finer nib for sketching purposes. Taking suggestions for FP #4, I want one with a flexible nib to develop more expressive handwriting with, and possibly also for artistic purposes.

Thank you!
