The ball-and-socket joints click together satisfyingly and hold tight even in complex shapes. I’ve already built a twisting spiral tower and a prism that catches the light from my window.

My kid has been building these crazy geometric shapes for hours—the ball-and-socket joints are surprisingly sturdy. I love how the flexible arches let you make curves that actually hold their shape.

The pieces click together firmly enough, but some of the flexible arches feel a bit too loose to hold complex shapes for long. It's fun to experiment with different structures, though I wish the connections had a tighter fit for more stable builds.
