Q: What converter would be compatable with this pen?

in this pen, it requires a standard international converter, but since the shape of the intake is slanted like a standard international cartridge, many of the chinese standard int'l converters won't work (since they're like cylinders with standard int'l bore, and not tapered). you're gonna wanna look for a standard international converter that has the smaller, slanted part at the front instead of just being a barrel. brands that do fit: schmidt (the K5), monteverde, montblanc, waterman, rotring, and some select moonman ones. brands that do NOT work (unless you're willing to file off some from the front to make it fit): jinhao, hero, penbbs, most chinese brands. basically any standard international converter that costs more than $5 will probably fit lol. i'd recommend the schmidt k5 because this pen has a schmidt nib/assembly, so it's like for sure compatible. if anyone finds a cheap chinese brand that has a properly shaped converter, please contact me because so many pens have this problem, and i want to buy 20 of them.

Q: What size nib us on this pen?

By comparing this with other pens I have, I would say this is a bit finer than 0.7mm (medium), but visually heavier than 0.5 (fine). Frankly, if it were near a fine nib, I wouldn't like it; and I like this pen a lot!

Q: What size is the nib?

It's a fine nib. Good flow. Smooth writing.

Q: Does it come with ink?

Yes, one ink cartridge is attached.
