What is painting pen?

A paint pen is a type of pen that contains water-based or oil-based paint. It is designed for use on various surfaces such as paper, fabric, glass, metal, plastic, wood, and ceramics. The paint is stored in the pen's chamber and flows through the nib when the user applies pressure. Paint pens come with different nib sizes and shapes, which allow the user to create different strokes and effects. They are widely used in art projects, DIY crafts, and artworks. The advantage of using paint pens is that they are easy to use and provide accurate and precise lines. The disadvantage is that the paint may dry out easily, and it is challenging to refill the pen.
