To use this building set, just open the reusable bag and start building! Let your child's imagination run wild with the 300 colorful blocks. Encourage them to stack the blocks to build towers, houses, or anything they can think of. The special pieces like flag blocks and the wheelbase can add extra fun and creativity to their builds. When your child is done playing, make sure to put all the blocks back into the bag. This helps keep the blocks organized and makes it easy to find them next time. To keep the blocks clean, you can wipe them with a damp cloth. Avoid using harsh chemicals as they may damage the blocks. Also, make sure small children don't put the blocks in their mouths to prevent choking hazards.
