Additional Information
Quercetti Intelligent Toys are specifically targeted for the ages 3 to 12 and are designed to encourage reasoning, creativity, mobility skills and cooperation among children. Each toy stimulates equally the right side of the brain (for fantasy, intuition, imagination) and the left side (for logic, math, language) to promote harmony and interrelation between the two sides and to teach children to think in a complete way. Our toys are never repetitive but always inspire new discoveries and inventions, helping children acquire new precious talents for their adult life. In brief, Quercetti Intelligent Toys help children's brains develop to the best of their potential.
