My boyfriends in the military, and always getting me surprises and I want to get him something that he can always wear or have with him. I want to get him an engraved ring, but don't know his ring size. He never wore any rings at home, so I have no way to guess. Any suggestions? I have a picture of him hands, but I'm not sure how well that will help.My boyfriends in the military, and always getting me surprises and I want to get him something that he can always wear or have with him.
