I tend to write really fast, and the flow of this pen is smooth enough to not make any noise during my hand movements

They need to dry for a minute on smoother surfaces, but no more than an ordinary felt pen, and they will bleed on thinner paper, or if you hold the tip down for too long, but that's why I like them, that means they have alot of free-flowing ink

They seem to keep a steady flow and I have used them on journals, in notebooks, and more.

This is in contract with when you first use one and the ink flows very well to the extent that it bleeds somewhat

It allows its user to create beautiful, precise flowing characters, while remaining a tried and true everyday writing implement
