Timeless self-assembly toy for children from 4 years old. Each set consists of high-quality beech wood engineered boards. Strong, colorful screws and plastic nuts, coupled with the large size of the elements and the simplified design, mean that children can experiment with engineering from an early age. The instructions are easy to follow. The sets are equipped with tools suited for small hands, enabling the child to repeatedly screw or disassemble the structure and then start again. The toy sets greatly influence the development of small motor skills, patience, and stimulate the imagination.
