One ring is used at a time, along with some other Single Polar accessory. 3 different size rings are supplied for size and fit variations. You can combine one scrotal ring and a Butt toy for an all round experience. Always use electro conductive gel with ElectraRings (not supplied).

The 3 sizes included in this pack. Sizes 52mm, 60mm, and 68mm diameter.

These are fairly Large sized rings.

Crafted from solid metal polished bar.

Can be used in conjunction with ElectraProbes.

All ElectraStim accessories come with a "Pin Connection"... so if you have wires from any of the Erostek or Folsom boxes that have the standard "Banana Plugs" at the end of your wires... you'll need to have a set of the adapters called "Banana to Pin" connectors (E105) to use with these accessories. http://www.mr-s-leather.com/E105.html

These are Single Polar rings, so you have to use either two rings or one ring and some other Single Polar accessory together.
