For anyone working as tirelessly as our firefighters do to protect us and our families, the Shields of Strength red line firefighter antique finish dog tag necklace is a touching gift. The beautiful zinc Christian jewelry features the words of Isaiah 6:8, "Then I heard the voice of the Lord saying,"Whom shall I send? And who will go for us?" And I said,"Here am I, Send me!" making it the perfect way to express love, thanks, and support for the men and women who make the world a safer place by putting their own lives on the line. The dog tag measures 1.95 inches by 1.08 inches and has an American flag with a red line motif on the front. The stainless steel ball chain measures 24 inches in length. To keep the necklace looking its best, wash with warm, soapy water or buff with a polishing cloth.
