A set of 4 adorable interactive picture books from the Piyo-chan series. ・Piyo-chan Says Thank You ・Where's Piyo-chan's Mommy? ・Good Night, Piyo-chan ・Piyo-chan's Friends These are picture books that I read to my children a lot when they were little. With gentle illustrations and heartwarming stories, these books are filled with interactive elements and were popular with my children. They have been stored at home for a long time, so there is some wear and tear, such as stains and folds. I have included pictures of the most noticeable pages (images 7-14), so please take a good look. Other pages are generally in good condition. There are no covers. If you understand the condition and are interested in using them for reading aloud, I would be happy if you would consider them. After simple cleaning and waterproofing, I will ship them via Yu-Yu Mercari. Thank you for looking. #InteractivePictureBooks #PiyoChan #SatoshiIriyama
