This convenient and portable set of watercolor pages is the perfect companion for the Niji Waterbrush, or any brush for that matter. Each 2 1/2" x 6 1/2" color sheet is a heavy layer of concentrated pure color coated on one side of a special paper fabric. Touch a sheet with a wet brush and you immediately pick up a clean, brilliant color or tear off a small piece from the sheet and lay on a plate or palette and add water. Colors flow smoothly and evenly and will travel compactly.
