quick overview :

Each 4” x 4” 3D shape is made of clear plastic with a colorful, plastic, folding net housed inside. The durable plastic nets are creased and folded to fit perfectly inside the matching shape—when unfolded, they sort of resemble mini gift boxes before they have been assembled. The bottom of each 3D shape contains the name of the shape, plus a removable panel for easy insertion and removal of the nets. The set contains 11 shapes in 6 different colors: a red triangular prism, a red triangular pyramid, a yellow square pyramid, a yellow cube, a purple rectangular prism, a blue pentagonal prism, a blue pentagonal pyramid, a green hexagonal pyramid, a green hexagonal prism, an orange cylinder, and an orange cone.
