I have tested the item before listing it, so please rest assured. There is no box or instruction manual. This is the cartridge only. There are traces of glue from a sticker that was removed from the back of the cartridge. Since this is a very old item, the battery may be dead, even if it was working during the operational check, depending on when you purchase it. I will clean the item and pack it carefully before shipping. I look forward to your purchase if you can rate the item promptly after it arrives. If you plan to purchase multiple items, please ask me in advance. I will relist them as a single combined item. Delivery is the next day for Honshu and the day after for areas outside of Honshu.
