My son got the celestial buddies Earth at the Air and Space Museum and they were inseparable. It has been loved and still looks new. We got this pack for the black hole and sun and moon, but with the price and the extra stuff it made sense. The book is great, can't wait to see the eclipse! Quality products and the size is nice. The black hole is much bigger than I thought, which is great because it holds the others. Overall, great purchase.
