– Soft edge eraser: Pressure sensitive eraser with a soft (blurred) edge. – Hard edge eraser: Completely erases whatever you want. – Textured pencil: The pencil I use the most because it has this realistic feel of pencil on paper – Customized hard edge pencil: Best for very accurate lines and clean work. NOTE: The Desktop and Windows 10 versions of the software are the only ones that support this brush set.
