Thank you for viewing. Purchased from Hamagakuen in the summer to autumn of 2025. It's released every summer to autumn, but would you like to get it a little early? Math and Science show signs of use, but I think they can still be used. The Japanese language materials are almost unused, so I think they are clean. However, these are used items, so please understand this before purchasing. When shipping, I will remove the rings and secure them with rubber bands. The rings will also be included to avoid adding to the thickness. I am not offering discounts. I want to sell everything, so I am not selling items separately. I am also not holding items. Thank you for your understanding.
