OLYMPUS Microscope CH Binocular Type (with box and accessories)

OLYMPUS CH Binocular Microscope, allowing for precise observation.
Although I am an amateur, I have confirmed its operation.
① The light turns on as shown in the 7th photo.
② Comes with a cover as shown in the 8th photo.
③ Includes a box, key, and some accessories as shown in the 9th-11th photos. However, I was unable to lock it (perhaps due to my method?).
It will be shipped in this wooden box, packed in a cardboard box with cushioning material.
