Kids will love to color this beautiful color-by-number butterfly artwork and hang it on their walls. This guided art activity will appeal to kids who are interested in art and want to create a "masterpiece". The numbered color guide is printed separately from the canvas to allow young artists to follow the guide or color the picture in their own creative way. The brightly colored Faber-Castell duo tip markers have a ventilated safety cap to prevent choking. The water-based inks wash out of most fabrics. The pen tips allow you to achieve 2 line widths: thin and broad.
