This collar is made from 3mm thick black heavy rubber and is cut with a curve to a point shape to show off the 50mm centre O ring with 2 large spikes on each side of the collar.

The buckle used is made from stainless steel (304/316) and the rivets used are nickel free. The spikes on our collars are held on by smooth headed screws for comfort against skin. They are made from stainless steel in Australia.
