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

These Single Metal rings are sold individually in 6 sizes.... These 6 sizes are not included in either of the two Ring Set Kits. EM2120 (5 Smaller Ring Set)..... OR EM2140 (3 Large Ring set)
