This is a set of all 12 DVD volumes of the Sign Language Introductory Course, which I purchased as a U-CAN learning material. I decided to study sign language a few years ago and took the introductory course from U-CAN. However, I ended up giving up halfway through, and I disposed of all the paper materials when I moved. Only the DVDs remained, and I couldn't bring myself to get rid of them. I no longer use them, and they're just gathering dust, so I'd like them to go to someone who can make use of them. I've decided to put them up for sale. They have been properly boxed and stored, so they are in good condition. I only studied up to around volume 6 or 7, as far as I remember, so all the volumes after that are unused. There are almost no scratches on the discs.
