Now you can dig for gold with the Kinetic Sand Buried Treasure set. Use the key hidden on the bottom of the playset to unlock your treasure chest. Inside, you'll discover a chest filled with Kinetic Beach Sand. As you dig through the sand (the key works as a shovel) searching for your treasure, you'll also find a layer of gold, onyx or silver Shimmer Sand. Dig until you uncover three bronze or silver coins, and you may even find the rare gold coin. Kinetic Sand is the original magical, moldable and mesmerizing sand. It flows through your hands and never dries out, so you can play again and again.
