XL Polydron Set 1 Starter Kit

XL Polydron is four times the size of Giant Polydron — properly big. Big enough that a tower becomes a castle, and a castle becomes something to crawl through.

This starter kit has squares and triangles with windows in them, which children tend to spend a long time peering out of. It connects with Giant Polydron too, so it grows if you add to it later.

Full-body, imaginative, slightly chaotic play. Good for burning energy indoors on a wet day.
