How to use: First, take out the action figures of Rubble and Mix and start imagining building scenarios. Then, pour the Kinetic Build-It Sand from the resealable container. Use the roller to flatten the sand and create imprints, or use the stamper to make building blocks. Let your creativity flow! Note: Keep the sand away from small objects that kids might accidentally swallow. Also, don't let the sand get wet as it may lose its moldability. Maintenance: After playing, put the sand back into the resealable container to keep it fresh and ready for the next play session. Wash the tools with mild soap and water if they get dirty.
