Two parenting books for sale as a set. "Papa is a Brain Researcher: The Neuroscience of Raising Children" Author: Yuji Ikegaya Price: 1760 yen "The Textbook of Parenting for Fathers" Author: Atsushi Shichida Price: 1650 yen I purchased these before and after childbirth and read each one once, then stored them on a bookshelf. The exteriors have some scratches, etc., but the insides are in good condition. There is a small crease on the corner of one page of "Papa is a Brain Researcher: The Neuroscience of Raising Children," but it shouldn't affect reading.
