Hello! I'm not quite sure what the purpose of this item is. Looks like it delivers electrical stimulation of some sort. It's definitely a cool old piece of 1950s or 1960s technology. It would make a great movie prop... maybe like a KGB torture device or something! Or..... you could hook your kid to it and tell them it's a vintage foolproof CIA lie detector you got from an old friend. Or..... If you have a cat you coul.... yea, that's going too far. Anyway, fast priority shipping. Thanks!
