Blu-ray Discs for Recording, BD-RE, 10 Discs Sony Corporation Capacity: 25GB 1-2X I recorded on these once for storage, but I never played them back, so I'm organizing them. I had some remaining stock on hand, so I took pictures, but I haven't checked them against the contents, so there's a possibility that items other than those in the last photo are mixed in. (For reference only---) I formatted (initialized) them from my computer. The protective cases aren't very clean. Thank you for your understanding. I plan to ship via Packet Post. Please purchase with the above in mind.
