The construction set consists of 193 parts, from which you can assemble 4 models: grader, truck crane, helicopter, truck. The complexity of the models has been increased, and there is an even greater variety of plastic parts. We recommend using the construction set both for home use and for group classes in kindergartens (from 5 years old) and in elementary grades. Playing with a metal construction set helps develop logical thinking, spatial representation and observation, and creating your own models is the basis for developing a child's creative thinking.
