"3-4 Year Old Wisdom Cards" Koharu Oi Price: ¥1400 Thank you for looking. I used it once and then stored it at home. The box has some scratches, but the contents are clean and without folds, and all the cards are present and in beautiful condition. I will sell it to someone who understands that it is a used item. *I will consider lowering the price depending on the situation. #Koharu Oi #book #society/education_and_learning #EarlyChildhoodEducation #Homeschooling
