Abstract
This product consists of sets of several or dozens of blocks in six different shapes: a cube, a half-size cube with approximately half the volume obtained by cutting a cube in half parallel to one of its faces, a rectangular prism with approximately twice the volume obtained by connecting cubes side by side, a cylindrical shape that fits perfectly into the size of a cube, a spherical shape, and a triangular prism obtained by cutting a cube in half along the same diagonal line on opposite faces. Each block has a regular arrangement of dot indentations on its designated face, which is intended to evoke the idea of systematically stacking and assembling blocks.
