A series of preschool toys where all it takes is one finger to put fantasy in motion: the cogs turn and set off an extraordinary chain reaction! The magic of the moving gears never wears off, and children never get tired of watching, at first, then taking them apart and putting them together again in completely new creations. This game guarantees many hours of fun playtime. And at the same time some basic principles of mechanics become clear. Educational fun with Quercetti gears.
