You never know what you'll find in Cornerstone's Mystery Bag! Nestled inside are fossils, rocks, and minerals just waiting to be discovered. Grab a plate, pour out the contents, and start digging for treasure. Having a small cup of water is handy, too, to rinse off your finds.
Each bag is guaranteed to contain at least 8 fun items to start your kiddo's geology collection.
Items may include:
Minerals: calcite, fluorite, pyrite grains, and tumbled stones
