No, I’m not a fan of those, actually. The brush fibers are way too limp, so I feel like I have no control like I’m drawing with a wet noodle.

EDIT: Actually, I’m not sure. I thought you were talking about one of these, which are just terrible.

Here’s what I used (tried to get detail of the brush fibers and name). I get them from a local art store. Maybe they are a cheap knock off of a Pentel or something, I can’t find them online.

The brush fibers are really stiff and nice, but the ink quality is not great, so I will probably move on, honestly. I’d love to know if you have any experience/opinions about any of them.
