The Koi Coloring Brushes from Sakura are a convenient way to add vibrant color to any sketch, journal, cartoon, illustration, or rubber stamps. These pens perform similarly to an artist brush, and contain bright dye-based ink. Make fine, medium or bold brush strokes just by changing the amount of pressure to the nib. The durable tip will quickly spring back to its original shape! The odorless, water-based solvent facilitates smooth blending and layering of colors. Transparent ink colors blend easily to create a multitude of hues and effects, and you can use the colorless blender pen to create seamless washes and color gradations.
