How to use: First, take out the colorful pieces from the set. Start by connecting the bars and metal balls to build a structure. Then, add the slides. Finally, roll your cars down the slides and enjoy the fun. Note: Keep small parts away from children under 3 to avoid choking hazards. When your child is done playing, store the pieces in a box to prevent loss. Maintenance: Wipe the pieces with a dry cloth if they get dirty. Don't soak them in water as it may damage the welded parts.
