The Rainbow Pyramid consists of ten cubes of different sizes that can be stacked on top of each other to form a stable tower. Each individual cube features various illustrations on its sides, including animal motifs, counting images, and clearly legible numbers from 1 to 10. The colorful design transitions harmoniously from violet and blue at the base, through green and yellow, to warm tones at the top. While stacking them, children can compare size proportions, name animals, and count quantities. After playtime, all elements can be nested inside one another to save space. Measuring 15 x 15 x 15 centimeters, the set is ideal for sorting, discovering, and playing together.
