Let your children be introduced to endless building possibilities with the K'NEX Rocket Car Building Set! This building set from K'NEX comes with 74 different rod and connector pieces, which can be assembled into 3D configurations. Kids can start with a rocket car to learn how K'NEX parts click together and then move on to the creations of their dreams. Easy-to-follow building instructions come along with the K'NEX Rocket Car Building Set. Unleash your kids' creativity as they make their own designs for open-ended fun! They can even combine the parts from this set with two other K'NEX building sets - Stealth Plane and Motorcycle - to create an amazing Helicopter combo build! This building set is recommended for kids ages 5 and up. Help your kids develop a better understanding of STEAM (science, technology, engineering, arts, and math subjects) with this building toy. As they click the parts together and discover how the building system works, they strengthen their hand-eye coordination, fine motor and problem-solving skills, and spatial awareness. K'NEX rods and connectors are responsibly made in America at a landfill-free, zero-waste green manufacturing facility in Hatfield, Pennsylvania. The strictest quality and safety standards were used in testing this toy to ensure that your child has a successful, trouble-free building experience. If you need a replacement for any broken or missing part, or for any other reason, just give us a call, and we will get you what you need so your child can get back to building as soon as possible.
