I found a lot of these while cleaning, so I'm selling them in smaller quantities. It says "sony corporation DVD-R for VIDEO ver.2.1/16X CPRM". This is a set of 10 discs. I don't think they're more than 10 years old, but they've been stored for a long time by a non-professional, so I'm selling them at a low price. The number of discs can be adjusted slightly, so please comment if you have a preference. Since I didn't have any cases, I purchased the non-woven fabric cases in the image for this listing, and two discs are placed back-to-back in each case. Please understand that there may be minor dirt, scratches, and dust that are unavoidable, and only purchase if you understand that these are used items. I plan to ship them as is, without any additional packaging, in a Yu-Packet Post Mini envelope.
