I accidentally bought two sets of the same items and was unable to return one because the cancellation deadline had passed, so I am selling one set. (It's dangerous to use your phone while half-asleep... I forgot I had bought it and bought it again the next day.) - Kodomo Roppo, 2nd Edition (List price: 1,300 yen + tax) - How to Use Kodomo Roppo (List price: 1,500 yen + tax) Total: 3,080 yen (including tax) Since the books are sealed, showing they are new, I only want to sell them as a set of two. I will ship via Takkyubin Compact with anonymous delivery. Thank you. Weekend sale: 2,300 yen -> 2,100 yen
