This deluxe kit is a real blast! 725 shapes will cover your ceiling with the starry sparkle of space. A star chart is included, so you can create classic constellations or make your own astronomical arrangements. You can even design new galaxies! A special phosphorescent formula gives these glow-in-the-dark stars a life that's almost as long as the real thing: they're rechargeable so they won't wear out. Just expose them to light and they're ready to glisten once more.
