Koi Coloring Brush Pen Woody Brown
These dye-based pens perform similarly to paint brushes. The artist can change the brush stroke thickness by altering the amount of pressure they apply while using. The nib automatically springs back to its original shape for easy coloring. The odorless water-based solvent lends to uniform blending and layering of colors. Experiment with creating unique colors with two or more pens or use either of the two sets for unlimited color combinations.
