Rollerballs generally use a thicker ink than a fountain pen. So when using the watery fountain pen ink, the tolerance between the ball and its housing has to be extra precise: too loose and then pen will leak, too tight and it won’t write. Most of the pens skew to the tight side, so they can feel a bit scratchy.
