It sure is. We selected this shape for many reasons. First, the military dog tag is the most recognized form of identification in the world. The shape (including the notch) is actually the same shape that was used for official military dog tags manufactured between 1941 and the early 1970's. This shape is looked upon with pride by those who served in the military and by most civilians as a symbol of the freedoms we enjoy today in America. The FIXX ID also allows you to engrave an image on the front side that is meaningful to you.
