Product Kenko • MIRROR SCOPE 500 Used item. Operational Check ・Since I do not have the environment or knowledge to check the operation, the operation has not been checked at all. ※Since the operation has not been checked, it is treated as a junk item. Please understand this beforehand. My grandfather was using it until a while ago, so I think it should be okay in terms of operation, but I don't know how to use it after receiving it, so I haven't been able to check the operation, so please don't rely on that too much. Returns are not accepted.
