Model Magic Shimmer is a much easier modeling material to work with than clay, making it great for kids. Unlike clay, Crayola Model Magic is lightweight and flexible after it air dries. While this set includes Black, White, Pink, Purple, and Blue, kids can blend colors together to create even more color options. The non-crumbling clay-like formula makes it great for long-lasting works of art, and the step-by-step instruction booklet helps kids get started.
