How Do You Use a Koi Brush Pen?

Koi brush pens have become a popular choice for artists and calligraphers alike due to their versatility in creating beautiful strokes of varying widths and textures. These pens are perfect for adding a touch of elegance to your lettering projects, illustrations, or even journaling. In this article, we’ll explore the basics of using a Koi brush pen and how you can get started with your own creations.

Getting Started

Before we dive into the techniques of using a Koi brush pen, let’s first get familiar with the tool itself. A Koi brush pen is essentially a marker that features a flexible brush tip instead of a regular nib. The bristles on the tip allow you to create varying line widths and textures by applying different levels of pressure as you draw.


To get started with using a Koi brush pen, you’ll need the following materials:

  • A Koi Brush Pen
  • Paper (preferably one that’s smooth and thick)
  • Pencil (optional)
  • Eraser (optional)


Now that you have your materials ready let’s take a look at some basic techniques that can help you create stunning artwork with your Koi brush pen.

Pressure Variation

One of the key features of Koi brush pens is their ability to create lines of varying thicknesses through pressure variation. By applying more pressure on the tip, you can create thick lines while applying less pressure will result in thinner lines. Experiment with different levels of pressure to see what works best for your project.

Angle Adjustment

The angle at which you hold your pen also plays an important role in creating different types of lines. Holding it at an angle will create thicker strokes while holding it straight up and down will create thinner strokes. Again, experimenting with different angles will help you find the right technique for your project.

Line Weight

Using a Koi brush pen, you can create lines of varying weights by adjusting the pressure and speed at which you draw. A slow and steady stroke will create a heavier line while a quick flick of the wrist will result in a lighter line.

Blending Colors

Another great feature of Koi brush pens is their ability to blend colors together. To achieve this, simply apply one color to the paper and then quickly add another color on top while the first color is still wet. The two colors will blend together seamlessly.


Here are some tips to keep in mind when using a Koi brush pen:

  • Practice makes perfect – don’t be discouraged if your first attempts don’t turn out as expected.
  • Experiment with different types of paper to see what works best for your style.
  • Use light pressure when beginning to avoid bleeding or smudging.
  • Clean your pen regularly with water or a cleaning solution to maintain its quality.


Koi brush pens are an excellent tool for artists and calligraphers who want to add some flair to their work. By following these techniques and tips, you can create stunning artwork that’s sure to impress. Remember, practice makes perfect so keep experimenting until you find what works best for you!
