Create Your Own World

K’NEX encourages kids to imagine, build, and play, with an exciting color-coded system of rods, connectors, and bricks that teaches valuable design and engineering principles while kids are having fun creating fantastic models. K’NEX is building worlds kids love, and we invite you to come along for the ride.

Made in the USA

Over the past 20 years, K’NEX has become America’s Building Toy Company with all of our bricks, rods, and connectors made in Pennsylvania at, its sister company, The Rodon Group’s manufacturing facility. K’NEX and Rodon proudly remain family owned and operated. At a time when most toys are made overseas we are committed to manufacturing as many parts in the United States as possible. You'll be happy to know that every rod and connector in this building set is made in the USA.

A Classic Building Experience

This set contains all full-scale (or “classic”) K’NEX pieces – the same kind that inventor Joel Glickman came up with as he was fiddling with straws at a wedding reception almost 25 years ago. All K’NEX parts and pieces are guaranteed for a lifetime of fun – we want to be around for amazing building experiences with your kids and theirs.
