K'NEX Big Ball Factory building set

This K'NEX set for the home is now discontinued.

However, you can still buy current K'NEX sets for the home.

K'NEX is one of the most successful construction kits in the world. It is based around a series of "Rods", which can be joined together by "Connectors", such as the one shown in our logo. Once they have mastered using these simple components, children and adults alike can use their
imagination to make potentially millions of different working models.

K'NEX parts are available in three different sizes, namely:

Micro K'NEX - the smallest size of K’NEX part, ideal for building roller coasters. Suitable for ages 7 to 11.

Classic K'NEX - the original size of K'NEX part, which can be used to build a wide range of different models. Suitable for ages 7 to 97.

Kid K'NEX - a version of K'NEX with larger, chunkier Rods and Connectors that small hands can easily join together. Suitable for ages 3 to 7.
