What It Is

With the K'NEX 35 Model Building Set, kids can follow the included guides to create 35 unique builds using the set's 480 pieces. Of those 35 builds, directions are included for 10 of them. The rest are available online using the included code in the instructions booklet. Pieces snap together easily and more importantly, stay together. The set features K'NEX classic and micro pieces.

Is It Fun?

This is a set that encourages a lot of open-ended construction play for kids. As you move through the guide the builds' difficulty level also increases, which is great for keeping builders engaged and challenged. Plus, the results are both eye-catching and perfect for tons of post-build play, such as the excavator with moveable parts.

Who It’s For

The K'NEX 35 Model Building Set is for ages 7 and up.

What To Be Aware Of

It took our expert builder 40 minutes to construct the excavator featured in the video. It will likely take the average builder a bit longer than that.

This set comes with a reuseable storage chest to store all your building pieces when playtime is over.
