A fun set of eight vibrant coloring-in tools for kids. Crayons go on silky smooth like a pastel (the colors are more vivid than a standard wax crayon) and deliver almost impossibly vibrant results. Extend playtime with window art (with parental permission of course), rock painting, and to create watercolor art you can simply add water with a paintbrush to create a water color effect. There is no mess as each crayon is housed within a twist-up tube to keep little fingers clean. Silk Crayons are non-toxic, odor free and water-soluble so stains are easily washed out. Ages 3 and up.
