Purchased on the Shichida Method website on April 28, Reiwa 7 (2025), and separated sheet by sheet. These are the latest materials as they were purchased recently. They have been carefully separated and scanned. While there are, of course, no noticeable folds or stains, there may be some minor creases. There are no writings or missing parts. We are looking forward to purchases from those who understand that the sheets have been separated. Although the sheets have been separated, there are no writings, so we are listing them as new and unused. We are also selling Thinking Skills Arithmetic Year 3 and Life 1.2. We offer a discount for combined purchases.
