PowerClix Clear is the ultimate architectural building kit.

In keeping with STEM toy attributes, PowerClix magnetic building toys encourage children to think like engineers while having fun. Children can build unlimited 3D forms by visualizing the underlying design structure of an object, then creating a wireframe model of it using magnetic frames of geometric shapes. Clear are designed to integrate flawlessly with all PowerClix system sets. Organize and store PowerClix pieces easily with the new metal plate built right into the packaging.
