I used these books for English speaking practice. The more you practice, the easier it becomes to think in English and speak fluently. The CDs are unopened. There is some wear and tear, but no writing inside. The blue book has a stain on the bottom, as shown in the photo. The contents are relatively clean, so these books are recommended for those who want to read the content and use the CDs. Please understand that these are used items.
