The O-Ring is attached to a tube 'runner' which is threaded onto the main body of the collar... this allows it to move freely not only up & down with the ring but from side to side. It can even be moved along the main body and be held at the back. Ideal for securing your loved one somewhere safe!
This collar can be made from Red or Black PVC with a choice of Black or Silver O' Ring... all look equally stunning.
It can be ordered in a very small collar size... perfect for the petite slave.
