These are DVD course materials from a course I took at Human Academy several years ago. I took multiple courses at the same time, so I don't remember exactly, but I believe it was a dog trainer/animal therapy course. The cases are bulky, so I've discarded them all, and only the discs remain. I've only watched them once or twice, so there are no major scratches, but there are some fine scratches and dirt on the discs as shown in images 2 and 3. Please refrain from purchasing if you are looking for a perfect product. I will ship them together in the black case shown in the image. No individual sales.
