This is a CD set for English study, containing a total of 6 CDs. However, only the first CD, ①, is missing. CDs 2 through 6 are unused. I bought this through mail order a few years ago for 19,800 yen. I tend to give up easily, so I didn't stick with it. But it was quite helpful, so I think it's definitely good for those who are going on a trip soon. - Set Contents: CD2, CD3, CD4, CD5, CD6 - - Brand: 7★English Thank you for looking.
