Konstrukta is a sustainable product because it is made from local wood and does not have any additional unnatural ingredients that would affect sustainability. The product has no coatings or adhesives. On the other hand, it is a toy for several generations and can be seen as something that is passed down from generation to generation in the family. Despite its age, the toy will still be relevant, unrepeatable and a challenge for new generations of children in a creative game that develops manual and mental skills, independent thinking, teamwork and interest in science and technology, i.e. STEM (science, technology, engineering and math) toys.
