① We Drained the Pond! A Book to Understand Invasive Species in Ponds ② Trick Art Amusement Park ③ Even Schools are Exciting These three books are a set. Target age: 6 years old and up, Elementary school students All books were purchased new at a bookstore and read by my child. I apologize, but the cutout of "Kasa Jizo" from the Trick Art Amusement Park book is missing. Thank you for your understanding. See photo 10. There are no scribbles or tears. They show some signs of use. Thank you.
