This is a set of Speed Learning volumes 1-28. The volume shown in the sixth photo is unopened, and the rest have been opened. There are also duplicate volumes. Regarding the opened volumes, I have confirmed that the titles and discs match, but I have not checked for playback. One title includes both an English-only disc and a disc with English and Japanese. In addition to the discs, booklets are also included, but some are unopened, some are opened, and some are missing. Please consider the above before purchasing. These items have been stored in a warehouse. There may be scratches and stains on the exterior due to storage. Please check the images.
