Show your true colors or critical first aid and first responder information with Voodoo Tactical patches. In an emergency, save time and lives with rubber patches backed with velcro that provide first aid professionals, medics and EMTs your blood type when you can't, or immediately identify yourself as law enforcement or first response personnel in an emergency or disaster situation. And, show your colors everywhere you go on clothing and gear with embroidered USA flag patches and Voodoo skull patterns.
