To use this Smartmax vehicle set, start by taking out the 13 colorful pieces. You can build 4 moving trucks by clicking the pieces together however you like. It's a great way to learn about magnetism and early engineering. When playing, make sure to keep small parts away from young children who might put them in their mouths. To maintain the set, wipe the pieces with a soft, dry cloth. If the pieces get dirty, you can use a mild soap and water, but make sure to dry them thoroughly. Remember, all SmartMax sets can be combined, so you can expand your collection and create even more amazing vehicles.
