Take four large colorful wooden boxes, then toss in three giant wooden marbles, and what do you get? A super fun, and endlessly fascinating game of balance and stacking for kids. Handmade in Germany by Grimm’s, these dancing boxes let children build whimsical structures with nesting boxes featuring holes on the side and bottom that allow the boxes to be carefully balanced on one of the pretty wooden marbles. Kids may also use the circular holes as windows or doors for a stuffed animal’s house or create a game by rolling the marbles into the smallest or largest box. Made with FSC certified sustainable wood and non-toxic paints, this set comes complete with 4 large nested boxes and 3 large wooden marbles.
