This brush pen is filled with water and can be used in combination with watercolor pencils to create shading and color blending.

It uses a watercolor brush, allowing for professional-quality painting. Simply fill the barrel with water and press the barrel to allow the water to penetrate the tip of the brush. This means there's no need for a bucket to store water.

It's quick and easy to set up, allowing you to create watercolor paintings.

The brush is also easy to clean; simply place a cloth over the tip of the brush and let the water flow, washing the brush in one go. As it doesn't use paint, even children can use it cleanly and without making a mess.
