What are the differences between brass & stainless steel Dog ID Tags?

The main difference between brass and stainless steel besides color is hardness. Stainless Steel is exceptionally harder than brass and therefore wears longer. There many factors that determine how fast the material of your dog tag will wear down. Here are a couple examples:

If you have a very active dog such as a hunting dog that is running through brush, etc. frequently, you may want to consider ordering a stainless steel ID Tag.

If your dog wears several tags that constantly rub against each other, this will eventually wear the metal down and make the engraving appear shallow.

Since brass is softer and does gradually wear down, over extended periods of hard use, the engraved characters on brass ID Tags may become more "shallow" and appear to fade as opposed to stainless steel which is more resistant to wear.
