The KINGART® Painting Pen is a metal pen with a well that holds inks or thinned acrylic paints. Ideal for students, hobbyists, and traveling artists, it can be used to draw fine lines in paintings, line drawings, and on signs. It can also be used for French matting — or even to touch up paint scratches on vehicles. The Kingart Painting Pen can be used on most surfaces, including fabric, wood, metal, and canvas. A cleaning tool is included with each pen. To clean, thoroughly clean the well and stem after each use by soaking them in warm water. To clean inside the stem, use the thin metal needle and push it through the stem. Rinse the pen and dry it thoroughly.
