Building Set
K’NEX building sets are a popular construction toy that allows kids and adults to build complex structures and machines. The sets consist of plastic rods, connectors, and other specialized parts that snap together to create a variety of models, from roller coasters and Ferris wheels to airplanes and robots. K’NEX sets come in a range of sizes and themes, from small sets for beginners to giant sets with thousands of pieces for advanced builders. They are designed to encourage creativity, problem-solving, and spatial reasoning skills while providing a fun and engaging building experience. K’NEX sets have been around for decades and continue to be a favorite among construction toy enthusiasts of all ages.
