Non-permanent water-based acrylic markers with full colors and a sturdy felt tip. You can use it on stone, paper, canvas, glass, porcelain, plastic, wood, cardboard and metal. Easily washable. With our creative multi marker you can draw on almost any surface and for kids it is the ideal marker for creative activities. The marker is not permanent, so you can easily wash it off the house with some soap and water. However, the paint is quite water resistant when dry, which is a huge advantage when painting on rocks. The marker also has a fixed felt tip, making it great for coloring. Important: Store flat with the cap on, but if the nib dries out, you can dot it on the paper until the ink flows back into the nib. The set consists of 6 markers with a line thickness of 4 mm.
