Data erasure completed. This is a set of 16 valuable SONY METAL-XR cassette tapes. They still look cool even now. Due to being sold individually at the same time, the actual number of tapes is less than the 17 shown in the image. The price will be adjusted accordingly. - Brand: SONY - Model: METAL-XR - Type: Type IV / Metal Position Some have lettering marks on the index, but they can be used by flipping them over. Thank you for looking.
