## Description

Building with K'NEX is easier than ever, with the beginner 40 Model building set! Featuring all new easy-build parts that allow children ages 5 and up to have a frustration-free building experience. The new parts – a barbell shaped rod that easily sandwiches between 2 connectors, and a flat panel piece that provides structural support – were specifically designed to address the needs of younger builders, who can easily build 2 flat shapes and then connect them together into a 3-D creation! Plus, newly designed wheels pop right on – they'll be on the go in no time! This set contains 141 parts and easy-to-follow, step-by-step building instructions and ideas for 40 different models. Your little builder can also use the parts to design and create from their own imagination! Packaged in a sturdy suitcase-style box with a handle for easy clean-up and portable storage. Building with K'NEX supports a child's developmental growth and puts them on a path towards a better understanding of STEM subjects. As they fit the pieces together, they're developing spatial awareness and honing their fine motor and dexterity skills. Give your child the gift of creativity with K'NEX and think outside the blocks!

## Features

- 141 PIECES – This set comes with 141 classic and micro K'NEX parts and pieces that "click" together, allowing kids to create anything that they can imagine.

The snap-fit pieces stick together securely and can be easily reassembled into other creations.
- BUILD & REBUILD – Includes an instruction booklet that shows builders how to create 40 unique models with its step-by-step guidelines like a car, a skyscraper, an airplane, a rowboat, and so much more!

Watch your kids’ imaginations grow through the sheer amount of models they can make with the K’NEX 40 Model Building Set.
