Be gentle when removing them from the book
Format: Board book, Format: Board book
My kids crazy about this book turning into toys. We are probably going to get the rest in the set. Gently push from the back when removing the pop out pieces to prevent the cardboard from tearing and separating from trying to dig them out. I don’t recommend the child put them together as a few were hard to push the pieces in and we bent a couple. Fine in the end but those aren’t going back into the book. They’ll just be room decor 😂
