I've used these pens and like them for drawing, particularly the .005 size. But I occasionally experience leaks from these pens that I have to discard them. I'll remove the cap and see a large puddle of ink at the base of the collar. It's happened on about 10% of the pens I've purchased over the past couple of years. JetPen is great about replacing them, but the problem is with the manufacturer.
