This is a DVD set sold under the catchphrase "You can speak English just by listening." There are 9 volumes in total. Volume 1 has been opened and listened to a few times, but the rest are untouched. The textbooks and booklets are also unopened from Volume 2 onwards. Volumes 2-9 are like new, but the plastic wrap has been removed, and they have been stored at home. Please be aware of this before purchasing. Thank you.
