Electronics Experiment Kit My Kit 150

This is a Gakken My Kit 150.
I found it while cleaning out my storage.

Everything shown in the photos is included. I am unsure if it functions correctly. Please check the photos for the condition of the item. It is being sold as-is (junk).

I would appreciate it if you would purchase it if you understand these conditions. I plan to ship via RakuRaku Mercari Bin.
