These are a great way to show the Ten Commandments--- abbreviated to the point to fit onto these 2 mil-spec stainless steel stamped dog tags. All parts are stainless steel. Dog tags are about 1.2 x 2". chains are 30" and 6". Chains can easily be shortened as desired by uncoupling, clipping, and recoupling (snap). Text is permanently embossed into the surface of the dog tags. You will LOVE these.
