Have you got an electro sex electrode you’re dying to try out but it comes with a 4mm socket and you’ve only got a 2mm connection lead wire? You can either buy another cable and try to keep it from tangling up with your other cables or you can use these genius 2mm to 4mm adaptors. The ElectraStim Adaptor Kit 2mm to 4mm allows you to quickly and easily change your 2mm pins to 4mm banana plugs. Simply slip an adaptor over each 2mm pin and then plug the new 4mm connection into your new electrode. You can even use these with two separate monopole items. For example, if you have a monopole penis plug with a 4mm connection and a monopole cock ring or a sticky pad with a 2mm connection you can now use both toys on the same channel! With the ElectraStim Adaptor Kit 2mm to 4mm set you can quickly convert one lead wire. If you have a dual channel power box that you would like to use an item with a 4mm connection, then you would need to purchase a kit for each lead wire.
