I’ve tired many paint markers and the Posca for fine tip and detailed work seems to last the longest. I like this product because it drys quick and had as a durable tip.

Not sure why but this size nib has a tendency to have a super sensitive needle valve. When you need to reload the nib- grab a piece of scrap cardboard. The chisel tips don't seem to have this problem, just the bullet point. Gotta love the opacity of posca though!
