Professor set. Some discs are selling at premium prices, exceeding the list price in the market. Some discs are relatively easy to obtain, but others take time to acquire, so if you want them all at once, please take this opportunity. The third photo shows the domestic version. The others are likely import versions. All discs were checked upon listing and were in good condition. However, the condition of the cases is not included. Please assume that the cases generally have scratches, cracks, and stains. Especially recent paper cases are prone to damage. Jacket photos and lyric cards also show signs of aging, so please understand. I don't smoke, and I don't have pets. Any noticeable scratches will be described and photographed separately. Due to the nature of used CDs, returns, refunds, and claims are not accepted, so please ask any questions you may have. Please refrain from purchasing if you do not have a reasonable understanding of used items. Shipping to overseas locations, remote islands, and special delivery areas will be charged to the recipient. Prepaid shipping is not available.
