Six Colour Balls by Grimms Rainbow
We were using unbranded balls for our marble runs up until we got these. These Grimm's balls are a game changer! They make a wonderful sound when rolling on wooden slats, rainbow arches or bridges and the kids love them. The colours are bright and vibrant and the perfect size for small hands.
6 Wooden Balls, perfect for playing with the Rainbow 10700 and the Large Set of Boxes 10370; the children can sort the colours.
Materials: made of maple wood, non-toxic water based color stain.
Size: diameter = 4,5cm.
