This large, sturdy set of 14 lattice-type models is crafted of wood spheres connected by metal rods, so it won’t break easily, even with frequent handling. Six vibrant colors identify each model with one of the six fundamental crystal systems: triclinic; monoclinic/base-centered; orthorhombic/base, face, body-centered; tetragonal/body-centered; rhombohedral; and hexagonal; cubic/face, body-centered. Each model is clearly labeled. Size: up to 6″.
