Princeton Brush Neptune Synthetic Squirrel Watercolor Brush, Round, 8

This is my go to quill brush! I have used it in my studio, plein air and when I am teaching. It holds water and pigment to cover large areas, yet a nice fine tip for details. The only drawback I find is that the wires that hold the plastic ferrule break quite easily. I know that this is because my handle swells, but when I am painting as much as I do each day, there is no time for it to dry out. Especially when I am competing at a plein air event.

Quality watercolor brush, versatile size with good water retention and paint pick-up; smooth execution and flow.
