This set allows you to experiment with electronic circuits, and you can build circuits by clamping wires to the springs. It's enjoyable for beginners to advanced users. The photos show an opened item, but the item I'm sending is unopened. - Model Name: Electronic Club 60 - Included: Instruction manual, wires, earphones Everything in the photos is included. It seems you can do 60 different experiments, but I haven't tried them all. Please prepare four manganese AA batteries. Thank you for looking.
