A set of a book of encouragement for mothers and a parenting manga for fathers. - Title: It's Okay, Mom - Title: Father Channel - ISBN: 9784902971077 - ISBN: 9784902971084 When my child was born, I bought all sorts of books that caught my interest. As you can see in the photo, there is a wrinkle on the inside back cover due to the thickness of the separate volume. I would be happy if someone who doesn't mind used items would purchase it. Since there are also shipping costs, I would appreciate it if you could refrain from negotiating a price reduction. Thank you for looking.
