One unused "Gakken Electronic Block EX-120" from Gakken, a vintage item. This set allows for experiments with a variety of electronic circuits. While a reproduction of the EX-150 was released, this is a valuable original from the Showa 50s (1975-1984). Required batteries (4x AA) are sold separately and are not included in this listing. I purchased this new 20-30 years ago and have kept it in storage ever since. The microphone component, which tends to show fingerprints, is still clean. I touched the main unit to check for the instruction manual, and it still has that unique new feel. I would like to keep it in as-new condition, so I have not tested its functionality. This is an old educational material using electronic devices. Please understand that there may be deterioration or malfunctions (it will be delivered as is). The polystyrene tray is mostly clean, but there is some dust-like dirt due to static electricity. In addition, the packaging has age-related dust and discoloration. I believe this is in a beautiful condition compared to other items currently available, but it is old, so please understand and confirm the condition beforehand. Shipping is included, and it will be delivered via anonymous delivery (Mercari shipping). ■ It will be sent via Yamato Transport Takkyubin (or Eco Mercari). If you prefer Yu-Pack, please contact me before purchasing. ■ If you live overseas, please use Mercari's official buyers such as Buyee or doorzo. The seller will not ship directly overseas. ■ Related words Summer vacation homework School materials Electrical circuit Experimental circuit Resistor Capacitor Switch Controller Science Physics Science experiment Experiment equipment Experiment kit Gakken Gakken Science Gakken Learning Science and Learning Electronic block Par Golf Mekamo Gakken Adult Science Educational manga Gakken manga Secret series Champion Course Gakken's Aunt Educational toys Showa toys Showa toys Showa Retro Memories Homework #Christmas #Christmas present #Showa toys #Showa toys
