This kit contains all you will need to make seven individual spheres perfectly balanced to create a mobile.  Spheres are 3" to 6 1/2" and precut for easy assembly.  The paper is partially recycled paper.  This kit is recommended for ages 12 and up.  It would be a nice project to make as a present for a friend. Made in USA!

You will also need two glue sticks, some string or heavy thread, and scissors to complete this project.
