Voodoo Tactical Blood Type O- Patch

This is a great idea for anyone, from LEO to soldiers or even everyday people. With this patch if you are ever in an accident the first responders will know your blood type in on quick glance. Our troops use tags like these so the medics and docs know their blood type. Equipped with Velcro this tag can go anywhere you go. Attach it to a vest, jacket or pants, and carry it on and off duty. A simple idea that might just save your life someday.
