This is a set of two pop-up books by Eric Hill. Published by Koronsha. This is the "Koro-chan's Surprise Box" series. My child enjoyed reading them very much. There is some damage, such as folds, on the pop-up parts. This is not suitable for those who are concerned about the condition. I am also listing many other good books. Bulk purchases are very welcome. Depending on the number of books, they may not fit in a Nekoposu due to thickness, so consultation may be necessary. Please feel free to contact me in the comment section.
