Thank you for viewing. I previously purchased this from Media 5 to master English vocabulary and idioms. Media 5 sells a version compatible with Windows 10. The price is 3300 yen. Although this product is somewhat old, it has been confirmed to be compatible with Windows 10 and 11. The content is the same. I will sell it at a low price. ▼ Vocabulary Book Important words and phrases are repeatedly studied in the vocabulary book.
