This will be English text. I don't know the content. The green packaged CDs are unopened (only one volume was opened for the photo). The others show signs of use. This is an item from a collection being sorted, and a tablet was included, so I don't know if it's related to the educational materials, but I will include it. (It has been started up) Since these are used items, please refrain from purchasing if you are concerned. Please take a look at the photos and consider. #English教材 #EnglishText
