A Norman & Jules favorite, this rainbow puzzle provides unlimited hours of creative, open-ended play. Children can assemble the pieces any way they want, and we've seen some truly creative arrangements from young visitors to our shop. Parents will be surprised at the number of shapes and structures into which their young ones can combine these 6 simple pieces. This puzzle is ideal for stimulating problem solving skills, spatial reasoning and open-ended play. Grimm's Spiel und Holz toys are lovingly designed and manufactured in Germany.
