One new MO disk will be included. *However, this is a bonus, so please be aware of the quality. The operation was confirmed about six months ago at a friend's house. Currently, I can't operate it myself, so the current operation is unknown (I think it's probably okay, but please understand that it's non-refundable and non-returnable). I think it's relatively clean for its age. A USB cable is included, but a DC5V AC adapter is not included. *However, it is a used item, so please be careful if you are very sensitive.
