What you say @tubamann2 about “… bracelet can really stand out” is most important. Diabetes, and any other condition could easily be missed by EMS Personnel if it is concealed in what appears to be fashion jewelry.
Another important place to have a hidden medical condition available for medical assistance is *the ICE app available on mobile phones. ICE = In Case of Emergency. In this app, which automatically defaults to the first position in “Contacts”, you can have your name and several contact persons listed along with all medical information you want to include. Also on my phone the home screen background is the inscription of my MedicAleart Bracelet with my medical file serial number; I’ve been a member of MedicAlert Foundation for over 50 years and always wear one of their bracelets.
