Military style dog tags are essentially tags that are crafted in the same way as tags that are used by the armed forces. These are often made using the same materials, made in the same shape and size, and sometimes marked the same way as their official military counterparts. While these can copy all of these from military tags, there are some things that you should probably not do when you customize tags that look like those used officially.
While you can actually write down similar information on your tags as those that are found on official ones worn by the many different divisions of the armed forces, it is probably not a good idea to have these made exactly the same for the purpose of defrauding people. Some people have been known to copy the formats of the tags that several military divisions use in order to trick some individuals into believing that they are indeed part of the US armed forces.

Tags can be customized in many ways, with options including materials used, size of the tags, thickness, and what is written on it. While military tags are marked using embossing, you can opt for other marking methods when you are having tags customized. You can have these printed using photosensitizing, stonewear process, and even digital printing. You can also use other marking methods like stamping, engraving, and etching.
There are many things that can be done with these tags, and these also include using the same kinds of chains as those used officially. Many people however choose to use other kinds of chains, with some opting for decorative ones since they had these made as accessories. You can also choose to use semi-precious metals for the chains used on these, like silver or even platinum. You can even opt for white gold chains for your decorative dog tags.
