I purchased this as a set about 15 years ago. I think the total cost was around 100,000 yen... Most of the CDs are included, and the unused ones are in multiple languages. Some of the booklets were used extensively and have stains and writing marks. Please check the photos. I'd like to sell these to someone who understands that they are used items. I also have flashcards and other items that I can't list here, so if you're interested in buying them all together or separately, I'll offer a discount. Please help me declutter my house! They were very expensive, so I can't just throw them away...
