Nice set with 6 pastel colors from the rich color palette of Koi. Koi Coloring Brush Pens are useful for adding vibrant color to sketches, journals, cartoons, illustrations or rubber stamps. The 48 transparent ink colors are easy to mix together to create countless shades and effects. Koi Coloring Brush Pens have a flexible, sturdy brush tip that allows you to easily draw different line thicknesses by adjusting the pressure on the tip. After use, the brush tip returns to its original shape.

The ink is water-based, so you can create beautiful color transitions by drawing different layers on top of each other or by holding the dots together. By holding the tips of two brush pens together you can easily mix the color because the ink flows from one point to the other. The ink can also be mixed with water for watercolor effects.
