The brief
The brand in a paragraph.
K'NEX was founded in 1992 in Hatboro, Pennsylvania. Joel Glickman created the brand. They manufacture plastic construction systems. Colorful rods and connectors snap together without tools. The building sets became known for structural engineering play. Kids built towers, vehicles, and machines from simple parts. K'NEX dominated the construction toy market through the nineties. Today the brand appears across 6,649 tracked brands globally. It ranks third in the Baby, Kids & Toys category. The systems remain popular in schools and homes worldwide. Simplicity and reusability defined their enduring appeal. The brand built something that lasted.
