Build beyond and create WOW with the K'NEX Imagine Creation Zone 50 Model Building Set. This set is a great starter kit and includes over 415 micro and classic scale K'NEX rods and connectors to build anything you can imagine. The enclosed step-by-step color-coded instructions get the builder started with 50 different unique builds. Builds vary in difficulty so you can build a patrol boat, dragon, school bus and more! And when the builder is done, all the K'NEX rods and connectors can be stored in the re-usable plastic storage tub. Most models can be built one at a time. Recommended for builders age 5 and older.
