The large Grimm's wooden balls in the rainbow colors are inspired by Montessori and Waldorf education. The wooden rainbow balls can be used like marbles for rolling, sorting and for self-built marble runs. Children from the age of 12 months get to know colors and shapes in a playful way. The rainbow-colored balls promote motor skills and imagination when building, sorting and plugging.
did you know that you can easily build a marble run, especially with the big Grimm's rainbows? To do this, lay the rainbows sideways and let the Grimm's balls roll on the groove between two arch elements. By placing the arch elements next to each other, a long, serpentine marble run is created.
ATTENTION: Not suitable for children under 1 year.
