This decorative construction toy consists of nine pieces and is designed to symbolize the smallest unit within a cell. It measures 10 cm cubed.

This spinning top, with a diameter of 4 cm, is available in pear, maple, cherry, walnut and plum woods.

These 16 blocks in bright colors are made of wood from ecologically supervised European forests. Famed Swiss toy designer Kurt Naef designed these blocks in 1957; they were his first toy design. The sophisticated but easy-to-use interlocking feature enables small children to build towers that don´t fall down. Older children can experiment with building cantilevered structures.
