2023 Edition Latest Version Disney English System Step by Step Blu-ray This is a set of 12 Blu-ray discs, Steps 1-12. They have been opened but are almost unused. Since there are many discs, I have checked with the Mickey Mate to see if they can play the beginning of each disc. As is a characteristic of Blu-ray, playback issues may occur depending on the device, so we do not guarantee playback on all devices. Please understand this before purchasing. Cancellations, returns, and refunds are not accepted. 7M
