One brush pen and two pencil brushes for Manga Studio 5 and Clip Studio Paint. I've been toying with these for the past two years and use these brushes almost exclusively in my illustration work. Use the sketchy pencil to compose your image, the soft pencil to plan details, and the brush pen for a smooth, natural finish.
