A set of replacement conductive rubber electrodes for the CB6000 style chastity cage (not the original). This is a set of two electrodes, one left and one right.

Easy to fit and cheap enough to make having a spare set on hand a good idea as, like all conductive rubber electrodes, the internal resistance rises over time.

I recommend using a good-quality electrogel with these electrodes for good skin contact.

These ones do not directly fit the official CB6000 cage, but rather the cheaper alternatives. It is possible to get them to fit the official CB6000 chastity cage, but that will require some tweaking with a craft knife.
