Our Thin Red Line American Flag pin is die struck from jeweler's metal, black enamel color filled with one stripe filled in a red enamel, and silver plated. “The Thin Red Line of Courage” represents the last ounce of courage firefighters find deep in their blood to conquer their darkest fears in order to save and protect life and property. This is the perfect pin to remember those who have placed their lives second to those they protect. Each of these pins include a standard clutch back to keep it secure on your jacket, badge or duffel bag. These come individually poly bagged.
