Limited-time final clearance sale! Retro microscope, boxed, beautiful item.

This is a very retro microscope that my family collected.
It appears to be in good condition with its original box, but I'm not sure how to test if it's working.
The box has some sticker residue on a few corners and what looks like tape marks on the back, but it otherwise seems to be in good condition.
These are shown in the last few photos.

For the reasons above, I am selling it at a low price, so please only purchase if you understand this.

The main unit is difficult to measure, so here are the box dimensions:
Width approx. 12cm x Height approx. 22cm x Depth approx. 8cm
