This is a very beautiful thick wooden toy! The base is a puzzle into four parts, each provided in the middle of a round stick, bristling with several square piques.Des, rectangles, circles and triangles in the pretty colors in monochrome, should be dragged around the sticks, but that requires turning them several times, to make them pass the obstacles posed by pics.L'enfant must perform several mental steps in order to parvenir.Beau and educational then!
