Koi brush pens have a flexible, sturdy brush tip, which allows you to easily draw different line thicknesses by adjusting the pressure on the tip.
After use, the brush pen returns to its original shape.
The ink is water-based, making it possible to create beautiful color transitions by drawing different layers on top of each other or by holding the dots together.
The ink is also miscible with water.
In addition to drawing, you can also do watercolor painting with the Koi Coloring Brush pens.
You can use the Koi brush pens for hand lettering, bullet journaling, illustrations, sketches, cartoons, coloring pages, Comic Art and so many more creative applications.
