So the above video is obviously Katie being locked into the new Tartarus collar. We’re pretty chuffed with this collar as I’m sure you’ll agree it is a beautiful item. Just like all our other collars it is made entirely from 316L grade stainless steel, the same metal used in body piercing jewellery, and has a very discreet locking mechanism with no small parts to lose. Even the ring is made from 316L stainless and there are an option of sizes. Plus on some models there is the option to engrave the collar too. If you like it as much as we do just go here to order one of your own.
