This set is for littler kids, softer to touch, and snap together a bit easier.
Bigger circumference on the posts, and they are flexible, indeed needing to be bent for many of the projects.
Not like the K’NEX for the older kids. Which are bit more rigid, are the regular ones, small and hard to snap together.
So… these K’NEX are better for 50 year old ornery old dudes too…
