Due to the nature of my work, I receive data on CDs, so I have a lot of empty cases. I believe they've basically only been used once. I can't confirm with the sender, though... Some have white backings and other variations, but I've gathered those that appear to be the same. A set of 50 costs just over 1000 yen plus shipping, which seems to be what major online shops are selling them for... This is a set of 12 transparent CD cases, perfect for storage. - Quantity: 12 - Type: CD Case - Color: Transparent Thank you for looking.
