CD series for learning everyday English, a set of 17 volumes. - Series Name: Speed Learning - Volumes: Volume 1 to Volume 17 - Content: Everyday English conversation - Format: DVD - Volume: Vol.1 to Vol.17 Thank you for viewing. This was used by my family. I have confirmed that all the CDs are present. I have not checked for any skipping issues. The textbook materials show some wear, such as creases from being opened, but I didn't find any writing when I quickly looked through them. Would you like to use them for English study?
