A fun picture book for learning about how machines work. - Title: Mekutte Manaberu Kikai no Shikumi Zukan (Lift-the-Flap Picture Book: How Machines Work) - Publisher: Gakken - ISBN: 978-4-05-204219-5 - Price: List price 1,980 yen Thank you for looking. I bought this for my child, thinking it would be fun because it clearly explains the mechanisms of familiar appliances like washing machines and vacuum cleaners, as well as large machines like airplanes and rockets, with illustrations that are revealed when you lift the flaps. However, it was only opened a few times. The cover has some scratches, marks, and edge wear, but the inside is in almost new condition with little sign of use. (One spot, the "refrigerator" flap, is slightly creased. See photo 7.) This item has been stored at home by a private individual. Please consider this before purchasing.
