Clean lines and even ink flow

That being said, with a few improvements it would be perfect!I am very particular about clean, fine lines, so these were an obvious choice.

They are not so slippery as a roller, more like the feel of writing with a fountain pen, not much pressure gets you a solid line.

They are comfortable to write all day and give s great end product with a fine line

Fine, smooth line and the ink doesn't bleed through the paper
