This listing is for a SKILCRAFT ELECTRONIC EXPERIMENT SET 100 (a re-branded Gakken EX-100). Item is used, but is in very good condition. It is complete (including manual) and working (see photo with lit light). The box shows some slight wear.

I had to clean some battery corrosion off of one of the connections and I cleaned the baking soda solution off as best I could. May need some additional fine cleaning.
