Gakken Otona no Kagaku (Gakken Adult Science) Electronic Block EX-150 Reproduction Edition Expansion kit: Light Experiment 60 It appears all the parts are present. The main unit is clean, but the box has some damage, so I've marked it as having some scratches and dirt. Operation has not been confirmed, but there is no rust on the battery box. Please be aware that operation is unconfirmed before purchasing.
