This is the KUMON Kumukumu Slope. Released by Kumon Publishing, this educational toy allows children to develop their creativity by freely combining 57 pieces of 18 different types of parts to create their own original courses. There is a guidebook, and you can build the course according to it, or you can create your own as you like. My child played with this when they were small, but they no longer use it, so I am selling it. All 57 pieces of the 18 types of parts are included, and the parts themselves have no scratches or stains and are in relatively good condition. (The box is partially damaged, and the guidebook is also slightly bent. Also, there were 12 balls to roll down the slopes, but 2 are missing. However, I think it is in perfect condition for use.) There are no noticeable stains or scratches, but please understand that this is a used item that children have played with. *All items have been wiped with disinfectant wipes. - Number of parts: 57 - Number of balls: 10 - Target age: 3 years old and up - Colors: Red, blue, green, yellow, white - Set contents: Slopes, balls, connecting parts, etc. - Manufacturer: Kumon Publishing I think it can still be enjoyed, so please consider it. #Kumon Publishing #Kumon #KUMON #EducationalToy #3 years old and up
