With 20 sides, the perfect icosahedron has the largest possible number of sides for a perfect polyhedron. This set allows you to build a sturdy icosahedron out of red quarter-circle pipes and black joints. The gently curved pipes make the icosahedron look more like a ball than a polygon. And of course, you can also use these parts to make other shapes!
