KUMON ① NEW Kumukumu Slope ② NEW Kumukumu Slope Expansion Parts (Jump & Ferris Wheel Set) ③ NEW Kumukumu Slope Expansion Parts (Volume Up Set) This is a 3-piece set (equivalent to 10,000 yen at the time of purchase). My child wasn't very interested, but I, the parent, got really into assembling it, and it ended up as interior decoration. So, I'm selling it to someone who needs it. All three items have boxes and instruction manuals. All the parts are present as shown in the photos. Everything has been wiped down with alcohol disinfectant wipes. The boxes will be folded and included. Please feel free to comment if you have any questions. If you don't have any questions, you are welcome to purchase immediately without commenting. Thank you.
