Using this scratch space drawing kit is super easy. First, take out one of the 8 space stencils and place it on the drawing surface. Then, use the included scratching tool to start creating your out - of - this - world space designs. When you're done with one stencil, you can switch to another to make a new design. For kids aged 3 and up, it's a great way to have fun and express creativity. Make sure to keep the scratching tool away from younger kids who might put it in their mouths. After use, store the stencils and the tool in a dry place to keep them in good condition.
