There are loads of companys out there on the net I got mine from www.sos-talisman.com you even get car skickers in case you crash and key rings etc and it’s world wide. I wear a watch type talisman discreet but essential. with my details inside. You can get them at a wide range of prices but I prefer the cheaper brand after all you don’t want to be mugged while unconscious do you??. It’s up to you shop around even at the local jewelers and your doctor will also help you. It really is a massive market for them and the choice is huge. Watches, pendants , bracelets etc etc.

Hope this helps
