They are pretty much as expected. They do come with 4 disposable ink cartridges, but I’d also recommend buying some ink, I also went with Rotring ink as well, I’m sure you could probably use any. They do come with refillable ink cartridges as well inside the pen. Make sure you shake the pen well to get the ink flowing through them, but don’t over do it, or else they will bleed. (Learned from experience.) but other than that they are great! The ink don’t smudge, or bleed, and it dries super quick. The likes are very sharp and smooth. The .10 pen it’s extremely fine so make sure you use it at a acute angle, or it might catch the paper. That’s all I can think of of the top. But I would recommend and they are quality!
