SAND THAT NEVER GETS WET: is a hydrophobic polymer, which means it's sand that never gets wet! It starts out as regular sand, but is then dyed and covered with a waterproof polymer to keep it dry. Little boys and girls use their imagination and creativity while building sand castles. It's great fun for kids of all ages and even adults. 

ENVIRONMENTALLY FRIENDLY MATERIAL: Made of safe, environmentally friendly, non-irritating and reliable high-quality materials, passed European and American safety testing standards, and obtained professional quality certification, providing children with a safer and protected play time. 

REUSABLE SCIENCE TOY GIFT: After playing with the sand, dry the sand completely with a paper towel and store it when completely dry, kids can use it to do science experiments or perform magic tricks! This is the best choice for Thanksgiving/Christmas/Birthday/Halloween gift. This is a fun interactive game.
