It also came with an ink converter thing which I might need if I use ink bottles.

Love a good fountain pen. Should cross post over to !fountainpens@lemmy.world
You can also refill the disposable cartridges with a syringe. The not-sharp variety for like irrigation or whatever are the best. Just be careful. Good writing!
When I do this, I seal them up again with a hot glue gun. Then I can put a few of them into my pencil case. You do have to be careful to not bump them around too much though — I did once have one of them leak when I was new to doing this (the benefits of nigh everything I own being black, I suppose)
Looks like a rollerball pen from this angle. Either way, those are really smooth and fun to write with.
The nib is sort of covered, so it looks that way. Added a closeup in the post.
Oh it’s one of those. Pretty cool and modern. I think it’s called a hooded nib.
