Princeton Brush Velvetouch Mixed Media Brush, Spotter, 5/0

As a hobby painter & student, I've seen cheap brushes fray & wear out, so now I'm sticking with Princeton. They're super-reliable keeping shape & tips whether loaded with water or more dry-brush. I especially like the long-rounds for details when my hands aren't steady. Velvetouch is my go-to line, although P Aqua Elite is pretty similar in performance. I also use a few P Neptunes-- those are really thirsty & hold lots of water, & they behave differently, but for some projects they're just what I need. Great quality & reasonably priced.
