A set of 10 very old Cabin Kogyo slide magazines, 36-capacity. The index is also blank, and there are no signs of use, so it's probably a dead stock item or something similar. I'm a layman and don't know anything more than this, so I'm asking those who have knowledge and can follow up on their own. It's been kept in a dormant state, and of course, there is no manufacturer's warranty. You will need to use it at your own risk, so I will list it as a display item for interior decoration.
