Painting with the Magic Marker and the white magic pen creates a magical effect, as the freshly painted color changes. The end of the pen shows the paint color, while the color on the cap corresponds to the result after painting over with the magic pen. With the 10 markers, you can paint in 20 colors. The markers have a non-deformable conical tip and are washable from most fabrics. The set includes 10 fiber markers and 2 magic pens, delivered in a hanging foldable box.
