A bulk set large enough to occupy a whole classroom, nursery or kindergarten.  Children will not only be able to build towers and rockets, but also tunnels to connect towers together.  They will love to use this outdoors and crawl from tower to tower whilst looking at their surrounding through the windows in the squares and triangles.  Giant Polydron and this XL Polydron set are compatible and can be used together with XL Polydron four times the size of Giant Polydron.  

This 36 piece set contains: 12 Squares with 16 Holes, 12 Squares with 4 Holes, 12 Triangles and a guide.  Sides of squares measure 40.5cm.  Age 2+.
